2012-11-05ARM: tegra30: clocks: add AHB and APB clocksJoseph Lo1-0/+46
Adding the AHB and APB bus clock for Tegra30. Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-10-16ARM: tegra: add tegra_timer clockSivaram Nair1-0/+1
This undoes commit 20f4665 "ARM: tegra: remove tegra_timer from tegra_list_clks" by bringing back the tegra_timer clock. tegra_timer is indeed a clock (hidden by the PERIPH_CLK macro) which should be added to the tegra_list_clks. The above commit caused tegra_init_timer() failing to get the clk reference.

2012-09-13ARM: tegra: introduce tegra_cpu_car_ops structuresJoseph Lo1-0/+3
The tegra_cpu_car_ops provide the interface for CPU to control it's clock gating and reset status. The other drivers should use this for CPU control. And should not directly access CAR registers to control CPU. Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-13ARM: tegra: clock: add connection name in i2c clock entryLaxman Dewangan1-5/+5
Add connection name "div-clk" for the i2c clock entry. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-13ARM: tegra: clock: add i2c fast clock entry in clock tableLaxman Dewangan1-0/+5
Tegra's i2c controller require two clock sources named as div-clk and fast-clk for proper operation. Currently, the entry of fast-clk is missing in tegra30 clock table and it is incorrectly named in the tegra20 clock table. Adds aliases to enable lookups for "fast-clk" to succeed. A later patch will remove the incorrectly named clock, once the driver is modified to use the new name.

2012-09-06ARM: tegra: remove tegra_timer from tegra_list_clksStephen Warren1-1/+0
tegra_time is a struct sys_timer, not a struct clk, so can't be included in an array of struct clk *. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-06ARM: tegra30: clocks: fix the wrong tegra_audio_sync_clk_ops nameJoseph Lo1-1/+1
It should use tegra30_audio_sync_clk_ops for tegra30. It will cause the tegra30 use the wrong audio_sync_clk_ops when build a kernel with a tegra20 and tegra30 both supported kernel. And building error when a tegra30-only kernel. Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-06ARM: tegra: clocks: separate tegra_clk_32k_ops from Tegra20 and Tegra30Joseph Lo1-1/+1
Currently the tegra20 and tegra30 share the same symbol for tegra_clk_32k_ops. This will cause a compile error when building a tegra20-only kernel image. Add tegra_clk_32k_ops for tegra20 and modify tegra30_clk_32k_ops for tegra30. Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-06ARM: tegra: Port tegra to generic clock frameworkPrashant Gaikwad1-731/+957
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.

2012-09-06ARM: tegra30: Separate out clk ops and clk dataPrashant Gaikwad1-0/+1144
Move clock initialization data to separate file. This is required for migrating to generic clock framework if static initialization is used. Signed-off-by: Prashant Gaikwad <pgaikwad@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
