tegra: Correct PLL access in ap20.c and clock.c

2012-07-07T12:07:19Z

Correct this warning seen by Albert: ap20.c:44:18: warning: array subscript is above array bounds There is a subtle bug here which currently causes no errors, but might in future if people use PCI or the 32KHz clock. So take the opportunity to correct the logic now. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: Add functions to access low-level Osc/PLL details

2012-05-15T06:31:37Z

Add clock_ll_read_pll() to read PLL parameters and clock_get_osc_bypass() to find out if the Oscillator is bypassed. These are needed by warmboot. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: fdt: Add function to return peripheral/clock ID

2012-03-29T06:12:48Z

A common requirement is to find the clock ID for a peripheral. This is the second cell of the 'clocks' property (the first being the phandle itself). Signed-off-by: Simon Glass Acked-by: Stephen Warren Signed-off-by: Tom Warren

tegra: add clock_ll_start_uart() to enable UART prior to reloc

2011-12-24T09:23:32Z

Most boards will want to enable a UART early. This function provides that feature in Tegra architecture code so the code does not need to be copied on every board. Signed-off-by: Simon Glass Acked-by: Stephen Warren Signed-off-by: Tom Warren

tegra2: Add more clock functions

2011-10-27T19:56:29Z

This adds most of the clock functions required by board and driver code: -query and adjust peripheral clocks -query and adjust PLLs -reset and enable control These functions are plumbed in as required. Signed-off-by: Simon Glass Tested-by: Tom Warren

tegra2: Rename CLOCK_PLL_ID to CLOCK_ID

2011-10-27T19:56:29Z

Rename CLOCK_PLL_ID to CLOCK_ID which takes account of the fact that the code now deals with both PLL clocks and source clocks. This also tidied up the assert() to match the one sent upstream, and fixes an error in the PWM id. Signed-off-by: Simon Glass Tested-by: Tom Warren

Tegra2: Add more clock support

2011-09-04T09:36:15Z

This adds functions to enable/disable clocks and reset to on-chip peripherals. Signed-off-by: Simon Glass
