clk: tegra: simplify periph clock data This patch determines the register bank for clock enable/disable and reset based on the clock ID instead of hardcoding it in the tables describing the clocks. This results in less data to be maintained in the tables, making the code easier to understand. The full benefit of the change will be realized once also other clocktypes will be table based.

clk: tegra: fix driver to match DT binding enum tegra*_clk is intended to match the IDs listed in the Tegra clock bindings. There are a few mismatches, which this patch fixes: 1) pll_s and cop were left out of the Tegra20 enum. 2) spdif_in and spdif_out were swapped relative to the Tegra30 binding. 3) i2cslow was misnamed as i2c_slow, and a duplicate i2cslow clock added to the Tegra30 enum.

clk: tegra: common periph_clk_enb_refcnt and clks This patch makes periph_clk_enb_refcnt a global array, dynamically allocated at boottime. It simplifies the macros somewhat and allows clocks common to several Tegra SoCs to be defined in a separate files. Also the clks array becomes global and dynamically allocated which allows the DT registration to be moved to a generic funcion. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>

clk: tegra: defer application of init table The Tegra clock driver is initialized during the ARM machine descriptor's .init_irq() hook. It can't be initialized earlier, since dynamic memory usage is required. It can't be initialized later, since the .init_timer() hook needs the clocks initialized. However, at this time, udelay() doesn't work. The Tegra clock initialization table may enable some PLLs. Enabling a PLL may require usage of udelay(). Hence, this can't happen right when the clock driver is initialized. To solve this, separate the clock driver initialization from the clock table processing, so they can execute at separate times.

clk: tegra: common periph_clk_enb_refcnt and clks This patch makes periph_clk_enb_refcnt a global array, dynamically allocated at boottime. It simplifies the macros somewhat and allows clocks common to several Tegra SoCs to be defined in a separate files. Also the clks array becomes global and dynamically allocated which allows the DT registration to be moved to a generic funcion. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>

clk: tegra: simplify periph clock data This patch determines the register bank for clock enable/disable and reset based on the clock ID instead of hardcoding it in the tables describing the clocks. This results in less data to be maintained in the tables, making the code easier to understand. The full benefit of the change will be realized once also other clocktypes will be table based.

clk: tegra: defer application of init table The Tegra clock driver is initialized during the ARM machine descriptor's .init_irq() hook. It can't be initialized earlier, since dynamic memory usage is required. It can't be initialized later, since the .init_timer() hook needs the clocks initialized. However, at this time, udelay() doesn't work. The Tegra clock initialization table may enable some PLLs. Enabling a PLL may require usage of udelay(). Hence, this can't happen right when the clock driver is initialized. To solve this, separate the clock driver initialization from the clock table processing, so they can execute at separate times.
