* ARM: ks8695: add board support for the OpenGear boards based on the KS8695Greg Ungerer2012-09-073-0/+243
| | | | | | | | | | | | | | | | | | A number of boards produced by OpenGear and based on the Micrel KS8695 SoC. Add board support to the KS8695 kernel code to support them. The following machine type entries will need to be added back into the mach-types file with these in mainline: cm4008 MACH_CM4008 CM4008 624 cm41xx MACH_CM41XX CM41XX 672 cm4002 MACH_CM4002 CM4002 876 im42xx MACH_IM42XX IM42XX 1105 im4004 MACH_IM4004 IM4004 1400 Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Olof Johansson <olof@lixom.net>

We experienced some issues while compiling some drivers as modules: Joachim has corrected several of them. We may reduce this number of exported values by reworking some drivers, in the future. Some drivers are also modified here, I would like to keep them in the series as the modifications are really related with our recent move to irqdomains or simply related with compiler annotations. I keep dmaengine Kconfig modification in this "fixes" series. The DMA driver will not be available for 9x5 SoC family otherwise. * tag 'at91-fixes' of git://github.com/at91linux/linux-at91: dmaengine: Kconfig: fix Atmel at_hdmac entry USB: gadget/at91_udc: add gpio_to_irq() function to vbus interrupt USB: ohci-at91: change annotations for probe/remove functions leds-atmel-pwm.c: Make pwmled_probe() __devinit ARM: at91: fix at91sam9261ek Ethernet dm9000 irq ARM: at91: fix rm9200ek flash size ARM: at91: remove empty at91_init_serial function ARM: at91: fix typo in at91_pmc_base assembly declaration ARM: at91: Export at91_matrix_base ARM: at91: Export at91_pmc_base ARM: at91: Export at91_ramc_base ARM: at91: Export at91_st_base

This will lead to missing the module wakeup on OMAP's where the smart idle wakeup is supported.

This causes breakage on multiple boards using uart pins for alternate functions. For example, on zoom3 random oopses can be seen with nfsroot as the smsc911x ethernet FIFO timings on GPMC bus are controlled by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these pads to uart4 functionality as commit 7496ba3 was doing. Not all boards tend to use all uarts and most of unused uart pins are muxed for other purpose. This commit breaks the modules which where trying to use unused uart pins on their boards. So remove the default pad muxing. Note that this is not a complete fix, as we now rely on bootloader set muxing for the uart wake-up events. Further patching is needed to enable wake-up events for uarts that are already muxed to uart mode.

The VENC interface previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and hence the OCPIF_SWSUP_IDLE flag was needed. Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is now "dss_ick". This allows the PRCM hardware to autoidle the VENC interface clocks when they are not active, rather than relying on the software to do it, which can keep the interface clocks active unnecessarily.

This commit caused a regression in the I2C hwmod reset on OMAP2/3/4, logging messages similar to these during boot: [ 0.200378] omap_hwmod: i2c1: softreset failed (waited 10000 usec) [ 0.222076] omap_hwmod: i2c2: softreset failed (waited 10000 usec) While the original patch was intended to fix some reset-related timing issues, it's believed that these problems were actually fixed by commit 2800852a079504f35f88e44faf5c9c96318c0cca ("ARM: OMAP2+: hwmod: Restore sysc after a reset"): http://marc.info/?l=linux-arm-kernel&m=133410322617245&w=2 Cc: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

Since the current hwmod sequence is accessing the sysconfig register just after the reset, it might lead to OCP bus error in that case. Add a new field in the sysconfig structure to specify a delay in usecs needed after doing a softreset. In the case of the ISS and FDIF modules, the L3 OCP port will be disconnected upon a SW reset. That issue was confirmed with HW simulation and an errata should be available soon. The HW recommendation to avoid that is to wait for 100 OCP clk cycles, before accessing the IP. Considering the worse case (OPP50), the L3 bus will run at 100 MHz, so a 1 usec delay is needed. Add an x2 margin to be safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This continues the theme started with vm_brk() and vm_munmap(): vm_mmap() does the same thing as do_mmap(), but additionally does the required VM locking. This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf.
