| * | ARM: tegra: don't exceed AVP limits when configuring PLLP | Jimmy Zhang | 2014-02-03 | 1 | -13/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | Based on the Tegra TRM, the system clock (which is the AVP clock) can run up to 275MHz. On power on, the default sytem clock source is set to PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to 408MHz which is beyond system clock's upper limit. The fix is to set the system clock to CLK_M before initializing PLLP, and then switch back to PLLP_OUT4, which has an appropriate divider configured, after PLLP has been configured Implement this logic in new function tegra30_set_up_pllp(), which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP clock switching. Remove the duplicate PLLP setup from pllx_set_rate() and adjust_pllp_out_freqs().

| * | Tegra: Fix MSELECT clock divisors for T30/T114. | Tom Warren | 2013-04-15 | 1 | -2/+2 |
| | | | | | | | | | | A comparison of registers between our internal NV U-Boot and u-boot-tegra/next showed some discrepancies in the MSELECT clock divisor programming. T20 doesn't have a MSELECT clk src reg. Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> | ||||
| * | Tegra30: Add AVP (arm720t) files | Tom Warren | 2013-01-16 | 3 | -0/+236 |
| This provides SPL support for T30 boards - AVP early init, plus CPU (A9) init/jump to main U-Boot. Some changes were made to Tegra20 cpu.c to move common routines into tegra-common/cpu.c and reduce code duplication.
