* Input: ep93xx_keypad - update driver to new core supportH Hartley Sweeten2009-12-151-9/+2
| | | | | | | | | | | | | | | | | | | | | This driver was merged before the ep93xx core support was added for the keypad clock and acquiring/releasing the necessary gpio's. Now that the proper support is in the ep93xx core this driver needs to be updated to work correctly. Summary of changes: 1) Remove some unused members from the platform data. 2) Remove the custom KEY macro and use the ones available in <linux/input/matrix_keypad.h> 3) Remove the keypad_{readl/writel} macros and just use __raw_{readl/writel} directly. 4) Update the clk_set_rate() call to work with the core support. 5) Cleanup the probe routine and remove some unneeded messages. 6) Use the ep93xx core functions to acquire and release the gpio's. 7) Fix the clk_get() call to get the keypad clock.

| | | | | | | | | | | | | | Add the core support needed by the ep93xx matrix keypad driver. The keypad driver unfortunately was merged early and the core support is missing. The clkdev support has been resolved and is now merged. This adds the platform device to the ep93xx core and supplies the functions needed to acquire/free the gpio pins and actually enable/disable the controller peripheral.

| | | | | | | | | | | | | | | | | | Update the ep93xx i2c support: 1) The platform init code passes the configuration data for the i2c-gpio driver. This allows any gpio pin do be used for the sda and scl pins. It also allows the platform to specify the udelay and timeout. 2) Program the gpio configuration register to enable/disable the open drain drivers. Note that this really only works if the sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and EP93XX_GPIO_LINE_EECLK. 3) Update the edb93xx.c platform init to use the new support.

* | [ARM] 5578/1: ep93xx: add ep93xx-keypad clockHartley Sweeten2009-07-091-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add clkdev support for the ep93xx_keypad driver. A matrix keypad driver for the ep93xx just got merged via the input subsystem group. For this driver to work the keypad clock needs to be added to the ep93xx clkdev support. In order to accomplish this the following changes are implemented: 1) Move the EP93XX_EXT_*_RATE defines to mach/include/hardware.h. 2) Add EP93XX_KEYTCHCLK_DIV{4/16} for the keypad driver. 3) Add support for programmable clocks (set_rate() callback). 4) Add clk_keypad for the keypad driver. 5) tab indent the clk_lookup table for easier reading. 6) Add the set_rate() callback to program the keypad clock. This callback is generalized since the ADC clock (touchscreen) can use the same callback. 7) Use the ep93xx_syscon_swlocked_write() core function for updating the software locked register.

* | [ARM] 5577/2: ep93xx: syscon locked register functionsHartley Sweeten2009-07-093-12/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add core functions to handle writes to the ep93xx software locked registers. There are a number of registers in the EP93xx System Controller that require a write to the software lock register before they can be updated. This patch adds a number of exported functions to the ep93xx core that handle this access. The software locked clock divider registers, VidClkDiv, MIRClkDiv, I2SClkDiv and KeyTchClkDiv would typically involve writing a specific value to the register. To support this the ep93xx_syscon_swlocked_write() function is provided. For the DeviceCfg register it's more typical to only need to set or clear a single bit. A generic ep93xx_devcfg_set_clear() function is provided to handle both operations. Two inline functions, ep93xx_devcfg_set_bits() and ep93xx_devcfg_clear_bits() are also provided to improve code readability. In addition, the remaining bits in the System Controller Device Config Register have been documented and the previously defined names shortened. All code paths that use this functionality have been updated except for arch/arm/kernel/crunch.c. That code is in a context switch path, which is not reentrant, so it is safe against itself.

It also allows the uart clocks to be stopped when there are no users.

This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

For each port, if interrupts are enabled, it is possible to debouce the input signal. Debouncing is implemented by passing the input signal through a 2-bit shift register clocked by a 128Hz clock. This patch adds a platform specific way to enable the debouce feature for these input ports.

* | [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-291-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

* | [ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre2008-11-281-4/+0
|/ | | | | | | | | | | | | | | | Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds defines for the external chipselect physical base addresses available with the EP93xx. These are meant to be used in the platform init code. In addition, documentation about the synchronous/asynchronous boot modes for the EP93xx and a reference to errata about issues with synchronous booting has been added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All EP93xx based systems can support Ethernet. This patch moves the platform_device setup from the various board support files into the core support file. The Ethernet driver data still remains in the individual platform setup files to allow specific platform configuration. This also adds Ethernet support to the edb9302, edb9312, and edb9315 platforms.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | Currently on the EP93xx platform early kernel messages go to UART1. Since this UART is the only one that has modem control signals it might be used for another purpose and it is undesirable for those messages to appear. This patch allows one of the other UARTs to be selected in the kernel configuration. It is assumed that the bootloader has configured and initialized the UART since this was the previous assumption.
