* ARM: tegra210: set PLLE_PTS bit when enabling PLLEStephen Warren2016-03-29-0/+2
| | | | | | | | This bit needs to be set for system suspend/resume to work. This setting will be documented in an updated TRM at some time in the future. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

| | | | | | | | | | p2371-2180 is the engineering board name for the Jetson TX1 developer kit. Update Kconfig description and help text to make this obvious to everyone.

* ARM: tegra: error check Tegra210 XUSB padctl waitsStephen Warren2015-11-12-5/+20
| | | | | | | | | Add code to detect timeouts when waiting for HW events such as PLL lock done. Any errors are logged and trigger an error return code. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

* ARM: tegra: switch Tegra210 to common XUSB padctlStephen Warren2015-11-12-158/+16
| | | | | | | | | | | | | This change simply deletes code from the Tegra210 XUSB padctl driver that is already present in the common XUSB padctl code. Since all the arrays in tegra210_socdata are empty, this update may leave the Tegra210 XUSB padctl driver non-functional at run-time. However, (a) this driver is not used yet so no regression can be observed and (b) the next commit will immediately fix this up.

* ARM: tegra210: implement PLLE init procedure from TRMStephen Warren2015-11-12-47/+132
| | | | | | | | | | | | Implement the procedure that the TRM mandates to initialize PLLREFE and PLLE. This makes the PLL actually lock. Note that this section of the TRM is being cleaned up to remove some confusion. The set of register accesses in this patch should be final, although the step numbers/descriptions might still change.

* ARM: tegra: clk_m is the architected timer source clockThierry Reding2015-09-16-6/+4
| | | | | | | | | | | While clk_m and the oscillator run at the same frequencies on Tegra114 and Tegra124, clk_m is the proper source for the architected timer. On more recent Tegra generations, Tegra210 and later, both the oscillator and clk_m can run at different frequencies. clk_m will be divided down from the oscillator.

* ARM: tegra: Implement clk_mThierry Reding2015-09-16-0/+11
| | | | | | | | | | On currently supported SoCs, clk_m always runs at the same frequency as the oscillator input. However newer SoC generations such as Tegra210 no longer have that restriction. Prepare for that by separating clk_m from the oscillator clock and allow SoC code to override the clk_m rate.

* tegra: Correct logic for reading pll_misc in clock_start_pll()Simon Glass2015-08-13-0/+7
| | | | | | | | | | | | The logic for simple PLLs on T124 was broken by this commit: 722e000c Tegra: PLL: use per-SoC pllinfo table instead of PLL_DIVM/N/P, etc. Correct it by reading from the same pll_misc register that it writes to and adding an entry for the DP PLL in the pllinfo table.

| | | | | | | | | | | | | Added PLL variables (dividers mask/shift, lock enable/detect, etc.) to new pllinfo struct for each Soc/PLL. PLLA/C/D/E/M/P/U/X. Used pllinfo struct in all clock functions, validated on T210. Should be equivalent to prior code on T124/114/30/20. Thanks to Marcel Ziswiler for corrections to the T20/T30 values.

* Tegra: clocks: Add 38.4MHz OSC support for T210 useTom Warren2015-08-05-2/+6
| | | | | | | | | | | | | | | Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs to be measured - should be close to 700MHz (1.4G/2). Note that some freqs aren't in the PLLU table in T210 TRM (13, 26MHz), so I used the 12MHz table entry for them. They shouldn't be selected since they're not viable T210 OSC freqs. Since there are now 2 new OSC defines, all tables (pll_x_table, PLLU) had to increase by two entries, but since 38.4/48MHz are not viable osc freqs on T20/30/114, etc, they're just set to 0.

* T210: Add support for 64-bit T210-based P2571 boardTom Warren2015-07-28-0/+7
| | | | | | | | | | | Based on Venice2, incorporates Stephen Warren's latest P2571 pinmux table. With Thierry Reding's 64-bit build fixes, this will build and and boot in 64-bit on my P2571 (when used with a 32-bit AVP loader). Signed-off-by: Tom Warren <twarren@nvidia.com>
* ARM: Tegra210: Add SoC code/include files for T210Tom Warren2015-07-28-0/+1648
| | | | | | | | | | | All based off of Tegra124. As a Tegra210 board is brought up, these may change a bit to match the HW more closely, but probably 90% of this is identical to T124. Note that since T210 is a 64-bit build, it has no SPL component, and hence no cpu.c for Tegra210. Signed-off-by: Tom Warren <twarren@nvidia.com>
* ARM: tegra: pinctrl: move Tegra210 code to the correct dirStephen Warren2015-03-30-0/+195
Patches that added the Tegra210 pinctrl driver and renamed directories arch/arm/cpu/tegra{$soc}-common -> arch/arm/mach-tegra/tegra-${soc} crossed. Move the Tegra210 pinctrl driver to the correct location. This wasn't detected since Tegra210 support is in the process of being added, and isn't buildable yet.
