2019-04-09clk: renesas: Synchronize Gen3 tables with Linux 5.0Marek Vasut
Synchronize R-Car Gen3 clock tables with Linux 5.0, commit 1c163f4c7b3f621efff9b28a47abb36f7378d783 . Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-12-03clk: renesas: Allow reconfiguring SDHI clock on Gen3Marek Vasut
The SDHI clock must be configured differently for HS200/HS400/SDR104 modes. Add support for reconfiguring the SDHI clock settings into the clock driver. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-06-01clk: renesas: Add PE clock handlingMarek Vasut
The PE clock have two parents, add support for picking the correct one and deriving the clock from it. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-06-01clk: renesas: Add PLL1 and PLL3 dividersMarek Vasut
Add and use the PLL1 and PLL3 dividers. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-06-01clk: renesas: Pass clock rate around as 64bit number internallyMarek Vasut
The PLL rate could be in the GHz range, which could overflow a 32bit data type. Since the hardware is 64bit anyway, pass the clock rates as 64bit number internally to avoid this. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-06-01clk: renesas: Fix swapped arguments in debug messageMarek Vasut
The mul and div arguments were reported in reverse order in the debug message, swap them to fix this. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-02-16clk: rmobile: Assure SD-IF clock are configured correctlyMarek Vasut
The SD driver calls clk_set_rate() before clk_enable(), yet clk_set_rate() implementation in the clock driver does not set the SD-IF divider. Fix it. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-01-24clk: renesas: Split out code shared between Gen2 and Gen3Marek Vasut
Pull code which is common for RCar Gen2 and RCar Gen3 into separate source file. No functional change. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-01-24clk: renesas: Split SMSTPCR and RMSTPCR tablesMarek Vasut
The Gen2 requires setting RMSTPCR before booting, while on Gen3 this is thus far always zero. Split the tables so the RMSTPCR can be set too. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-01-24clk: renesas: Make PLL configurations per-SoCMarek Vasut
Not all SoCs have the same PLL configuration options, so make those PLL configuraion tables per-SoC. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-01-24clk: renesas: Make clk_ids per-driverMarek Vasut
Not all drivers use the same IDs, so make those IDs per-driver. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2018-01-24clk: renesas: Split RCar Gen3 driverMarek Vasut
Split the massive driver into smaller per-SoC drivers and pull the common code into a separate file. This would allow configuring out unnecessary clock drivers once the Kconfig changes are in and also allow adding more clock tables easily.

2017-12-09clk: rmobile: Fix typo in R8A7796 RPC clock table entryMarek Vasut
Fix a copy-paste typo in the clock table entry, s/7795/7796/. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2017-11-30clk: rmobile: Add R8A7796 xHCI clockMarek Vasut
Add xHCI entry into the clock tables, so that the xHCI USB driver can enable the clock for the xHCI block via clock framework. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2017-11-30clk: rmobile: Move preboot clock shutdown to the driverMarek Vasut
The MSTP registers were poked in boards/renesas/rcar-common/common.c in arch_preboot_os hook thus far to shut down the clock before Linux takes over. With DM, this is no longer needed and we can do the same in the clock driver .remove callback. This patch adds such a .remove callback for R8A7795 and R8A7796.

2017-09-24clk: rmobile: Add support for setting SDxCKCRMarek Vasut
The SDxCKCR must be configured correctly, otherwise the SDIF can be unstable. This is done in board files thus far, but those are going away, so move the setting of SDxCKCR into the correct place.

2017-08-26clk: rmobile: Split R8A7795 and R8A7796 core clock tablesMarek Vasut
The R8A7795 and R8A7796 tables use different constants to identify clock in DT, so split the tables and use the correct constants on R8A7795. This fixes UART clock misconfiguration on R8A7795.

2017-08-03clk: rmobile: Add RCar Gen3 clock driverMarek Vasut
Add clock driver for the RCar Gen3 R8A7795 and R8A7796 SoCs . This driver allows reading out the clock configuration set by previous boot stages and enabling and disabling clock using the MSTP registers. Setting clock is not supported thus far.
