2013-02-05ARM: i.MX25: clk: parent per5_clk to AHB clockSteffen Trumtrar1-0/+3
The mxc-timer on the imx25 needs to be derived from the AHB clock. If a bootloader reparents this clock to the ipg_clk_highfreq, which according to the datasheet is a valid operation, the system can/will produce lockups/ freezes after some time [1]. This can be forced with code like while(1) syscall(SYS_clock_gettime, CLOCK_REALTIME, &tp); This was already fixed with the commit "i.MX25 GPT clock fix: ensure correct the clock source" [2], for 3.1-rc2, but was lost, when i.MX was converted to the common clock framework ("ARM i.MX25: implement clocks using common clock framework") [3] [1]: http://lists.arm.linux.org.uk/lurker/message/20130129.161230.229bda17.en.html [2]: 2012d9ca2a1381ae3e733330a7f0d1d2f1988bba [3]: 6bbaec5676e4f475b0d78743cbd4c70a8804ce14 Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Cc: stable@vger.kernel.org # v3.5+ Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2013-01-18ARM: i.MX clock: Change the connection-id for fsl-usb2-udcPeter Chen1-3/+3
As we use platform_device_id for fsl-usb2-udc driver, it needs to change clk connection-id, or the related devm_clk_get will be failed. Signed-off-by: Peter Chen <peter.chen@freescale.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Felipe Balbi <balbi@ti.com>

2012-11-12ARM i.MX25: Add missing clock gatesSascha Hauer1-8/+55
This completes the list of clock gates on the i.MX25. There are several clocks marked as reserved in the datasheet, but nevertheless used in the Freescale kernel. Add some comments to their positions and add 'reservedx' entries to the clk enum. This way we can replace them with the real names should we need them later. Adding the reserved entry names will help us keeping the clk numbers when moving to devicetree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2012-10-15ARM: imx: include hardware.h rather than mach/hardware.hShawn Guo1-3/+2
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".

2012-10-15i2c: imx: remove cpu_is_xxx by using platform_device_idShawn Guo1-3/+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.

2012-09-18ARM i.MX25: Make timer irq work againSascha Hauer1-1/+1
Since i.MX has SPARSE_IRQ enabled the i.MX25 timer is broken. This is because the internal irqs now start at an offset of NR_IRQS_LEGACY. The patch fixed this up, but missed the i.MX25 timer which used a hardcoded value instead of a define. This patch introduces a define for the timer irq and uses it. This is broken since introduced with 3.6-rc1: | commit 8842a9e2869cae14bbb8184004a42fc3070587fb | Author: Shawn Guo <shawn.guo@linaro.org> | Date: Thu Jun 14 11:16:14 2012 +0800 | | ARM: imx: enable SPARSE_IRQ for imx platform Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Shawn Guo <shawn.guo@linaro.org>
2012-09-11ARM: clk-imx25: Fix SSI clock registrationFabio Estevam1-4/+2
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.
