When changing a PLL's rate, it must have no active children. The CPU clock cannot be stopped, and CPU clock's divider is not used. The old clock driver used to handle this by internally reparenting the CPU clock onto a different PLL when changing the CPU clock rate. However, the new common-clock based clock driver does not do this, and probably cannot do this due to the locking issues it would cause. To solve this, have the Tegra cpufreq driver explicitly perform the reparenting operations itself. This is probably reasonable anyway, since such reparenting is somewhat a matter of policy (e.g. which alternate clock source to use, whether to leave the CPU clock a child of the alternate clock source if it's running at the desired rate), and hence is something more appropriate for the cpufreq driver than the core clock driver anyway.

This patch converts tegra clock code to generic clock framework in following way: - Implement clk_ops as required by generic clk framework. (tegraXX_clocks.c) - Use platform specific struct clk_tegra in clk_ops implementation instead of struct clk. - Initialize all clock data statically. (tegraXX_clocks_data.c) Legacy framework did not have recalc_rate and is_enabled functions. Implemented these functions. Removed init function. It's functionality is splitted into recalc_rate and is_enabled. Static initialization is used since slab is not up in .init_early and clock is needed to be initialized before clockevent/clocksource initialization. Macros redefined for clk_tegra. Also, single struct clk_tegra is used for all type of clocks (PLL, peripheral etc.). This is to move quickly to generic common clock framework so that other dependent features will not be blocked (such as DT binding). Enabling COMMON_CLOCK config moved to ARCH_TEGRA since it is enabled for both Tegra20 and Tegra30. Signed-off-by:

A U16 divider can divide a clock by 1..64K. However, the range-check in clk_div16_get_divider() limited the range to 1..256. Fix this. NVIDIA's downstream kernels already have the fixed range-check. In practice this is a problem on Whistler's I2C bus, which uses a bus clock rate of 100KHz (rather than the more common 400KHz on Tegra boards), which requires a HW module clock of 8*100KHz. The parent clock is 216MHz, leading to a desired divider of 270. Prior to conversion to the common clock framework, this range error was somehow ignored/irrelevant and caused no problems. However, the common clock framework evidently has more rigorous error-checking, so this failure causes the I2C bus to fail to operate correctly. Signed-off-by:

Some boards use UART D for the main serial console, and some use UART A. UART D's clock is listed in board-dt-tegra20.c's clock table, whereas UART A's clock is not. This causes the clock code to think UART A's clock is unsed. The common clock framework turns off unused clocks at boot time. This makes the kernel appear to hang. Add UART A's clock into the clock table to prevent this. Eventually, this requirement should be handled by the UART driver, and/or properties in a board-specific device tree file. Signed-off-by:

Andreas Bombe reported that the added ktime_t overflow checking added to timespec_valid in commit 4e8b1452 ("time: Improve sanity checking of timekeeping inputs") was causing problems with X.org because it caused timeouts larger then KTIME_T to be invalid. Previously, these large timeouts would be clamped to KTIME_MAX and would never expire, which is valid. This patch splits the ktime_t overflow checking into a new timespec_valid_strict function, and converts the timekeeping codes internal checking to use this more strict function.

[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).
