* ARM: imx: move clock drivers into drivers/clkShawn Guo2015-06-031-313/+0
| | | | | | | | After the cleanup on clock drivers, they are now ready to be moved into drivers/clk. Let's move them into drivers/clk/imx folder. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Stephen Boyd <sboyd@codeaurora.org>
* ARM: imx: remove inclusions of platform headersShawn Guo2015-06-031-3/+17
| | | | | | | | With the cleanup done before, we now can simply define base address and irq as needed in clock driver, to get those platform header inclusions removed. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx: add clk-pllv1 type supportShawn Guo2015-06-031-2/+2
| | | | | | | | | Instead of calling cpu_is_xxx() in clk-pllv1 driver, let's add clk-pllv1 type support to handle the difference/quirk in particular SoC designs. Doing so will help get clk-pllv1 driver ready for being moved out of arch/arm/mach-imx folder. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx: use dynamic mapping for CCMShawn Guo2015-06-031-1/+4
| | | | | | | Replace the static mapping of CCM block in clock drivers with dynamic mapping. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx: use dynamic mapping for timerShawn Guo2015-06-031-1/+1
| | | | | | | | Pass physical address of timer block to mxc_timer_init() call, which in turn does dynamic mapping within the function. Thus, we can avoid using static mapping in clock drivers. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

* ARM: imx35 Bugfix admux clockMarkus Pargmann2013-04-091-0/+1
| | | | | | | | | | | | | 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.

* ARM: clk-imx35: Bugfix iomux clockMarkus Pargmann2013-04-091-0/+1
| | | | | | | | | | | | | | | | | 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.

* ARM: i.MX35: enable MAX clockSascha Hauer2013-03-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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: Sascha Hauer <s.hauer@pengutronix.de>

* i2c: imx: remove cpu_is_xxx by using platform_device_idShawn Guo2012-10-151-3/+3
| | | | | | | | | | | | | | | | | | | 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.
