The admux clock seems to be the audmux clock as tests show. audmux does not work without this clock enabled. Currently imx35 does not register a clock device for audmux. This patch adds this registration. imx-audmux driver already handles a clock device, so no changes are necessary there.

This patch enables iomuxc_gate clock. It is necessary to be able to reconfigure iomux pads. Without this clock enabled, the clk_disable_unused function will disable this clock and the iomux pads are not configurable anymore. This happens at every boot. After a reboot (watchdog system reset) the clock is not enabled again, so all iomux pad reconfigurations in boot code are without effect. The iomux pads should be always configurable, so this patch always enables it.

The i.MX35 has two bits per clock gate which are decoded as follows: 0b00 -> clock off 0b01 -> clock is on in run mode, off in wait/doze 0b10 -> clock is on in run/wait mode, off in doze 0b11 -> clock is always on The reset value for the MAX clock is 0b10. The MAX clock is needed by the SoC, yet unused in the Kernel, so the common clock framework will disable it during late init time. It will only disable clocks though which it detects as being turned on. This detection is made depending on the lower bit of the gate. If the reset value has been altered by the bootloader to 0b11 the clock framework will detect the clock as turned on, yet unused, hence it will turn it off and the system locks up. This patch turns the MAX clock on unconditionally making the Kernel independent of the bootloader. Signed-off-by: NSascha Hauer <s.hauer@pengutronix.de>

It moves a bunch of header files included in hardware.h and itself from mach-imx/include/mach to mach-imx, and updates users to include hardware.h rather than mach/hardware.h. The files in mach-imx/devices will need to include "../hardware.h".

It changes the driver to use platform_device_id rather than cpu_is_xxx to determine the controller type, and updates the platform code accordingly. As the result, mach/hardware.h inclusion gets removed from the driver.

This is some amount of work left/forgot from device tree conversion. Instead of checking cpu_is_xxx to determine the controller type, the driver should use platform_device_id, which should match the device tree compatible string. The patch changes the driver to use platform_device_id rather than cpu_is_xxx to determine the controller type/version. It also updates the platform code and device tree source accordingly. As the result, mach/hardware.h inclusion gets removed from the driver.

SSI block has two types of clock: ipg: bus clock, the clock needed for accessing registers. per: peripheral clock, the clock needed for generating the bit rate. Currently SSI driver only supports slave mode and only need to handle the ipg clock, because the peripheral clock comes from the master codec. Only register the ipg clock and do not register the peripheral clock for ssi.
