clk: tegra: Remove CLK_M_DIV fixed clocks Tegra has no CLK_M_DIV2 and CLK_M_DIV4 clocks and instead it has OSC_DIV2 and OSC_DIV4 clocks from OSC pads which are the possible parents of PMC clocks for Tegra30 through Tegra210. Tegra PMC clock parents are changed to use OSC_DIV clocks. So, this patch removes CLK_M_DIV fixed clocks Tested-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Sowjanya Komatineni <skomatineni@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

clk: tegra: Support for OSC context save and restore This patch adds support for saving OSC clock frequency and the drive-strength during OSC clock init and creates an API to restore OSC control register value from the saved context. This API is invoked by Tegra210 clock driver during system resume to restore the OSC clock settings.

clk: tegra: Properly include clk.h Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Only include clk.h in files that are using it. Also add in a clkdev.h include that was missing in a file using clkdev APIs.

clk: tegra: Model oscillator as clock Currently the Tegra clock driver simplifies the clock tree somewhat by taking advantage of the fact that clk_m runs at the same frequency as the oscillator. While that's true on all currently supported SoCs, it does not apply to Tegra210 anymore. On Tegra210 clk_m is typically divided down from the oscillator frequency. To support that setup, add a separate clock for the oscillator that both clk_m and pll_ref derive from. Modify the tegra_osc_clk_init() function to take an additional divider parameter for clk_m. Existing SoCs always pass in 1, whereas Tegra210 will read the divider from a register in the clock & reset controller. Signed-off-by: Thierry Reding <treding@nvidia.com>
