mx53: Make PLL2 to be the parent of UART clock

2012-03-27T07:41:17Z

Change the parent UART clock to be PLL2, so that U-boot can also boot a Freescale 2.6.35 kernel for mx53. FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid conflicts with IPU clocks, so that the video resolution can be changed without affecting the UART clock. On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded and this patch fixes this problem. Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.

i.mx: i.mx5: update imx_get_mac_from_fuse function

FEC does not work on the i.mx51/53evk board, it will hangup In: serial Out: serial Err: serial Net: After bisect, it due to the following commit: be252b6 net: imx: Add multi-FEC support for imx_get_mac_from_fuse has change the imx_get_mac_from_fuse fucntion prototype, but fail to update i.mx5, here it does it.

i.mx: introduce the armv7/imx-common folder

2011-12-09T16:30:10Z

In order to support the coming MX6 platform and to reducde the duplicated code, we had better move some common files or functions to the imx-common folder for sharing. This patch does the following: - move speed.c file from armv7/mx5/speed.c to armv7/imx-common/speed.c - move armv7/mx5/timer.c to armv7/imx-common/timer.c, no any new feature added but just fix the checkpatch errors in the old file and remove the CONFIG_SYS_MX5_CLK32 reference in the file - create one new file cpu.c file to store the common function with i.mx5/6 Signed-off-by: Jason Liu Cc:Stefano Babic Acked-by: Stefano Babic

mx5: Correct a warning in clock.c

2011-12-06T22:59:39Z

This corects the warning below, obtained with my gcc 4.6 compiler. arch/arm/cpu/armv7/mx5/libmx5.o: In function `decode_pll': arch/arm/cpu/armv7/mx5/clock.c:94: undefined reference to `__aeabi_uldivmod' I am not able to test this on MX5x hardware, but it does improve the MAKEALL output for me. You may already have a similar patch, but I cannot see it on the list. Signed-off-by: Simon Glass

mx53: Turn off child clocks before reconfigure perclk_root

2011-11-04T21:06:37Z

In addition to ensuring that PERCLK remains at least 2.5 times slower than the AHB clock, certain steps need to be followed to ensure robust operation of PERCLK when reconfiguring the PERCLK clock source. To properly configure the PERCLK clock source, the following steps are required: 1.In the CCGR registers, gate the clocks to all PERCLK-dependent modules. 2.Select the desired input clock for the PERCLK root clock (to be either source from the peripherals main source clock or the lp_apm clock source). Refer to the CMCBR register, perclk_lp_apm_sel bit. 3.Configure the perclk_pred1, perclk_pred2, and perclk_podf dividers to the desired setting. Refer to the CBCDR register for details. 4.In the CCGR registers, enable the desired clocks for the PERCLK-dependent module clocks. If these steps aren't followed, GPT timer may stop and the kernel stops at "Calibrating delay loop". Signed-off-by: Terry Lv Signed-off-by: Fabio Estevam
