This adds to the basic clock functionality already available. The concept of a peripheral ID is introduced, and all peripheral clock access is done using this ID.
Functions are provided to start, query and adjust peripheral clocks, including automatic selection of the best available clock based on the requested rate (this replaces hard-coded divisors). On the pinmux side we can now select functions for pin groups using the new pinmux_set_func() function. Expanded functions are provided to adjust and query PLL clocks. With a full compliment of clock and pinmux functions, it should no longer be necessary for board/driver code to directly access clock registers. This change removes all such accesses. This functionality will be used for I2C, SPI, LCD, USB, keyboard, NAND and other drivers for Tegra2. At then end is a patch to enable MMC on Seaboard, to make it all worthwhile. Note: These patches include a definition of assert() which I will happily remove if the one sent upstream is accepted. Changes in v2: - Remove assert() which is now in common.h Simon Glass (6): tegra2: Rename CLOCK_PLL_ID to CLOCK_ID tegra2: Clean up board code a little tegra2: Add more clock functions tegra2: Rename PIN_ to PINGRP_ tegra2: Add more pinmux functions tegra2: Enable MMC for Seaboard arch/arm/cpu/armv7/tegra2/ap20.c | 5 +- arch/arm/cpu/armv7/tegra2/clock.c | 825 +++++++++++++++++++++++++++- arch/arm/cpu/armv7/tegra2/pinmux.c | 528 ++++++++++++++++++- arch/arm/include/asm/arch-tegra2/clk_rst.h | 84 +-- arch/arm/include/asm/arch-tegra2/clock.h | 149 ++++- arch/arm/include/asm/arch-tegra2/pinmux.h | 444 ++++++++++----- board/nvidia/common/board.c | 243 +++------ board/nvidia/common/board.h | 4 +- board/nvidia/harmony/harmony.c | 26 + board/nvidia/seaboard/seaboard.c | 35 ++- drivers/mmc/tegra2_mmc.c | 94 ++-- drivers/mmc/tegra2_mmc.h | 1 + 12 files changed, 1950 insertions(+), 488 deletions(-) -- 1.7.3.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
