* ARM: imx6sl: Add missing pll4_audio_div to the clock treeNicolin Chen2013-12-311-2/+3
| | | | | | | There's a dividor for pll4_audio clock missing in clock tree, thus add it. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: imx6: Derive spdif clock from pll3_pfd3_454mNicolin Chen2013-12-312-0/+6
| | | | | | | | | | SPDIF can derive a TX clock for playback from one of its clock sources -- spdif root clock to match its supporting sample rates. So this patch set the spdif root clock's parent to pll3_pfd3_454m since the pll3_pfd3_454m can approximately meet its sample rate requirement.

* ARM i.MX5: set CAN peripheral clock to 24 MHz parentMarc Kleine-Budde2013-12-311-0/+3
| | | | | | | | | | | | This patch sets the parent of CAN peripheral clock (a.k.a. CPI clock) to the lp_apm clock, which has a rate of 24 MHz. In the CAN world a base clock with multiple of 8 MHz is suited best for all CIA recommented bit rates. Without this patch the CAN peripheral clock on i.MX53 has a rate of 66.666 MHz which produces quite large bit rate errors.

| | | | | | | | | | | | | | | Add machine support code for the Freescale IMX50 SoC. The IMX50 is quite similar to the Freescale IMX53, and contains many of the same periperhal hardware modules, at the same address offsets as the IMX53. (Notable exceptions are that the IMX50 contains no CAN bus hardware, less GPIO, no VPU, it does contain an Electrophoretic display controller though).

However, this change missed the detail that the bitops require an "Ir" constraint rather than an "er" constraint ("I" = integer constant from 0-31, "e" = signed 32-bit integer constant). This would cause code to miscompile if these functions were used on constant bit positions 32-255 and the build to fail if used on constant bit positions above 255.

Currently the shared DTS file provides "vmmc" and "vmmc_aux", and the supply lookup will fail: smsc911x 2c000000.ethernet: Looking up vdd33a-supply from device tree smsc911x 2c000000.ethernet: Looking up vdd33a-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed smsc911x 2c000000.ethernet: Looking up vddvario-supply from device tree smsc911x 2c000000.ethernet: Looking up vddvario-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed Fix it! Looks like commmit 6b2978ac40e4 (ARM: dts: Shared file for omap GPMC connected smsc911x) made the problem more visible by moving the smc911x configuration from the omap3-igep0020.dts file to the generic file. But it seems we've had this problem since commit d72b4415011e (ARM: dts: omap3-igep0020: Add SMSC911x LAN chip support). Tested on OMAP3 Overo platform.

This fixes WLAN on omap4-sdp that got broken in v3.10 when we moved omap4 to boot using device tree only as I did not have the WL12XX card in my omap4 SDP to test with. The commit that attempted to make WL12XX working on omap4 SDP was 775d2418f309 (ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for blaze).

So, move wl12xx_* to omap4_pmx_core. Fix the following error message: pinctrl-single 4a31e040.pinmux: mux offset out of range: 0x38 (0x38) pinctrl-single 4a31e040.pinmux: could not add functions for pinmux_wl12xx_pins 56x SDIO card is not detected after moving pin mux to omap4_pmx_core since sdmmc5_clk pull is disabled. Enable Pull up on sdmmc5_clk to detect SDIO card. This fixes a regression where WLAN did not work after a warm reset or after one up/down cycle that happened when we move omap4 to boot using device tree only.

This issue disappears when reducing the internal frequency of the TWI IP. Even if it is indicated that internal clock max frequency is 66MHz, it seems we have oversampling on I2C signals making TWI believe that a transfer in progress is done. This fix has no impact on the I2C bus frequency.
