* ARM: pxa: remove platform dma codeRobert Jarzmik2016-08-091-1/+0
| | | | | | | | | As the last pxa related driver was converted to dmaengine, it's time to kill the legacy dma code, which is not used anymore. This finishes the pxa dmaengine transition. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

| * ARM: pxa: define clock registers as __iomemArnd Bergmann2016-02-012-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should not dereference registers as pointers, so use readl/writel instead for these registers. The clock registers are accessed in multiple files, so we have to change them all at once. I stumbled over these registers while looking at something unrelated. There are in fact other registers with the same problem, but I did not try to address those at this point.

* | usb: gadget: pxa25x_udc: move register definitions from archArnd Bergmann2016-03-041-163/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ixp4xx and pxa25x both use this driver and provide a slightly different set of register definitions for it. Aside from that, the definition in the ixp4xx-regs.h header conflicts with the on in the pxa27x device driver when compile-testing that: In file included from ../drivers/usb/gadget/udc/pxa27x_udc.c:37:0: ../drivers/usb/gadget/udc/pxa27x_udc.h:26:0: warning: "UDCCR" redefined #define UDCCR 0x0000 /* UDC Control Register */ ^ In file included from ../arch/arm/mach-ixp4xx/include/mach/hardware.h:27:0, from ../arch/arm/mach-ixp4xx/include/mach/io.h:18, from ../arch/arm/include/asm/io.h:194, from ../include/linux/io.h:25, from ../include/linux/irq.h:24, from ../drivers/usb/gadget/udc/pxa27x_udc.c:23: ../arch/arm/mach-ixp4xx/include/mach/ixp4xx-regs.h:415:0: note: this is the location of the previous definition #define UDCCR IXP4XX_USB_REG(IXP4XX_USB_BASE_VIRT+0x0000) This addresses both issues by moving all the definitions into the pxa25x_udc driver itself. It turns out the only difference between them was 'UDCCS_IO_ROF', and that could well be a mistake when it was incorrectly copied from pxa25x to ixp4xx.

| * ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmodeArnd Bergmann2015-10-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The z2 machine calls pxa27x_set_pwrmode() in order to power off the machine, but this function gets discarded early at boot because it is marked __init, as pointed out by kbuild: WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode() The function z2_power_off() references the function __init pxa27x_set_pwrmode(). This is often because z2_power_off lacks a __init annotation or the annotation of pxa27x_set_pwrmode is wrong. This removes the __init section modifier to fix rebooting and the build error.

* | ARM: pxa: fix DFI bus lockups on startupRobert Jarzmik2015-09-131-0/+7
|/ | | | | | | | | | | | | | | | | After the conversion of pxa architecture to common clock framework, the NAND clock can be disabled on startup if no nand driver claims it. In this case, it happens that if the bootloader used the NAND and set the DFI arbitration bit, the next access to a static memory controller area, such as an ethernet card, the system bus will stall, and the core will be stalled forever. Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit will be enabled the pxa3xx-nand driver on need anyway. The only left requirement is that upon pxa3xx-nand removal, the bit should be cleared before the clock is disabled. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

| * arm: pxa: move init functions into generic.hRobert Jarzmik2014-11-193-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to have a unique .c file for all pxa variants device-tree definitions, all the initialization functions for MACHINE_START and DT_MACHINE_START have been put together into generic.h. The alternative would have been one pxaXXX-dt.c file per variant. The move is necessary because each include/mach/pxaXXX.h includes the variant register descriptions which intersects and conflicts one with each other. The change is a preparation for pxa-dt.c to support multiple pxa, ie. pxa3xx and pxa27x. The machine files including mach/pxaXXX.h all include generic.h, which guarantees no regression should be introduced.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 2111667b4677 ("ARM: pxa: call debug_ll_io_init for earlyprintk") triggers in the current kernel the attached backtrace on PXA/tosa early in the boot time when DEBUG_LL is enabled. It is due to overlap between uart virtual memory defined in DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus mapped by pxa_map_io at the same address, 0xf2100000. As hinted by Arnd, map early virtual memory for low level debug on address 0xf6200000, even if that means 2 virtual mappings will give access to the pxa internal UARTs (FFUART, BTUART, STUART, ...). ------------[ cut here ]------------ kernel BUG at /home/lumag/linux/mm/vmalloc.c:1143!

So we take a sweep over these, and for every such header that uses PXA_NR_BUILTIN_GPIO or PXA_GPIO_TO_IRQ() we explicitly #include "irqs.h" so that we satisfy the dependency in the board include file alone.

* | ARM: pxa: fix USB gadget driver compilation regressionLinus Walleij2013-12-281-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" a compilation error was introduced in the PXA25x gadget driver. An attempt to fix the problem was made in commit b144e4ab1ef130e8bf30bcd3e529b7f35112c503 "usb: gadget: fix pxa25x compilation problems" by explictly stating the driver needs the <mach/hardware.h> header, which solved the compilation for a few boards, such as the pxa255-idp and its defconfig. However the Lubbock board has this special clause in drivers/usb/gadget/pxa25x_udc.c: This include file has an implicit dependency on <mach/irqs.h> having been included before <mach/lubbock.h> was included. Before commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" this implicit dependency for the pxa25x_udc compile on the Lubbock was satisfied by <linux/gpio.h> implicitly including <mach/gpio.h> which was in turn including <mach/irqs.h>, apart from the earlier added <mach/hardware.h>. Fix this by having the PXA25x <mach/lubbock.h> explicitly include <mach/irqs.h>.

Currently the device is not instantiated on the centro unless CONFIG_MACH_TREO680 is defined. This patch eliminates the #ifdefs, and uses the machine_is_* macros to initialize the data based on which machine the code is running on and the build-time configuration. Unused data is optimized out by the build tools if build configuration does not enable support for both machines.

The precise role of each gpio in the hardware architecture is not entirely clear to me; this patch is the result of trial-and-error and observing how the PalmOS code initializes the lcd. The need for this patch is not evident when Linux is loaded from PalmOS, because at that point the lcd-related gpios have already been configured.

* | ALSA: pxa27x: fix ac97 warm resetMike Dunn2013-01-081-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.
