2012-02-27ARM: imx6q: add cko1 clockRichard Zhao
- add DEF_CLK_1B to define clocks using one bit gate - add cko1 clock and set ahb as the default parent imx6q-sabrelite board use it as audio codec clock. Signed-off-by: Richard Zhao <richard.zhao@linaro.org> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-01-20ARM: imx6: add missing twd_clk for imx6q clockShawn Guo
With commit 5def51b (ARM: 7211/1: smp_twd: get the rate from a clock) hitting mainline, if we do not have a twd_clk for lookup, we will see the following error message in boot log. smp_twd: clock not found: -2 Actually we should add this clock regardless of the error message, so that we can: * Avoid the local timer calibrating at boot time * Make the local timer cpufreq aware on imx6q Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-01-05ARM: 7198/1: arm/imx6: add restart support for imx6qShawn Guo
The restart support was missed from the initial imx6q submission. The mxc_restart() does not work for imx6q. Instead, this patch adds the restart for imx6q. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-11-17ARM: imx6q: move clock register map to machine_desc.map_ioRichard Zhao
map_io is the only place to call iotable_init. Signed-off-by: Richard Zhao <richard.zhao@linaro.org> [shawn.guo: rename imx_clock_map_io() to imx6q_clock_map_io()] Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2011-11-11arm/imx: fix imx6q mmc error when mounting rootfsShawn Guo
The following error is seen in some case when mounting rootfs from SD/MMC cards. Waiting for root device /dev/mmcblk0p1... mmc1: host does not support reading read-only switch. assuming write-enable. mmc1: new high speed SDHC card at address b368 mmcblk0: mmc1:b368 SDC 3.74 GiB mmcblk0: p1 mmc1: Timeout waiting for hardware interrupt. mmcblk0: error -110 transferring data, sector 3678224, nr 40, cmd response 0x900, card status 0xc00 end_request: I/O error, dev mmcblk0, sector 3678225 Buffer I/O error on device mmcblk0p1, logical block 458754 lost page write due to I/O error on mmcblk0p1 This patch fixes the problem by lowering the usdhc clock and correcting watermark configuration.
