[PATCH 18/36] pinctrl: sh-pfc: r8a7795: Fix VIN versioned groups

Biju Das <biju.das.jz@...>
 

From: Jacopo Mondi <jacopo+renesas@jmondi.org>

commit 184844ccda4138402846bf4b42c28ac5f16a458a upstream.

Versioned VIN groups can appear on different sets of pins. Using the
VIN_DATA_PIN_GROUP macro now supports proper naming of said groups
through an optional 'version' argument.

Use the 'version' argument for said macro to fix naming of versioned
groups for the R-Car H3 R8A7795 SoC.

[PATCH 12/36] clk: renesas: cpg-mssr: Mark clocks as critical only if on at boot

Biju Das <biju.das.jz@...>
 

From: Ulrich Hecht <uli+renesas@fpond.eu>

commit ed4a11807d2a35ccfc0d00371f20b826f670b5f2 upstream.

This allows us to add the RWDT clock to the list of critical clocks without
keeping it enabled needlessly if not used.

Changing the semantics of crit_mod_clks in this way is safe for the current
user (INTC-AP) because it is never off at boot time.

[PATCH 13/36] clk: renesas: rzg2: Mark RWDT clocks as critical

Biju Das <biju.das.jz@...>
 

From: Ulrich Hecht <uli+renesas@fpond.eu>

commit 52bc5ea6edde35bc65ed6ecd7639534e78002c74 upstream.

Ensures RWDT remains alert throughout the boot process if enabled.

This patch applies the change to the following SoCs: r8a774a1,
r8a774b1 and r8a774c0.

[PATCH 19/36] pinctrl: sh-pfc: r8a7795-es1: Add I2C{0,3,5} pins, groups and functions

Biju Das <biju.das.jz@...>
 

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

commit e244ff6f913f6ce4c77a00647462bc34c4221f46 upstream.

This patch adds I2C{0,3,5} pins, groups and functions to
the R8A7795 ES1.x SoC.

These pins are physically muxed with other pins. Therefore, setup of
MOD_SEL is needed for exclusive control with other pins.

[PATCH 17/36] pinctrl: sh-pfc: r8a77965: Fix DU_DOTCLKIN3 drive/bias control

Biju Das <biju.das.jz@...>
 

From: Geert Uytterhoeven <geert+renesas@glider.be>

commit a34cd9dfd03fa9ec380405969f1d638bc63b8d63 upstream.

R-Car Gen3 Hardware Manual Errata for Rev. 2.00 of October 24, 2019
changed the configuration bits for drive and bias control for the
DU_DOTCLKIN3 pin on R-Car M3-N, to match the same pin on R-Car H3.
Update the driver to reflect this.

After this, the handling of drive and bias control for the various
DU_DOTCLKINx pins is consistent across all of the R-Car H3, M3-W,
M3-W+, and M3-N SoCs.

Fixes: 86c045c2e4201e94 ("pinctrl: sh-pfc: r8a77965: Replace DU_DOTCLKIN2 by DU_DOTCLKIN3")

[PATCH 11/36] clk: renesas: rcar-gen3: Allow changing the RPC[D2] clocks

Biju Das <biju.das.jz@...>
 

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit 0d67c0340a60829c5c1b7d09629d23bbd67696f3 upstream.

I was unable to get clk_set_rate() setting a lower RPC-IF clock frequency
and that issue boiled down to me not passing CLK_SET_RATE_PARENT flag to
clk_register_composite() when registering the RPC[D2] clocks...

[PATCH 09/36] clk: renesas: rcar-gen3: Add RPC clocks

Biju Das <biju.das.jz@...>
 

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

commit db4a0073cc82a95d8d1a9b05fde82355fcce77d8 upstream.

The RPCSRC internal clock is controlled by the RPCCKCR.DIV[4:3] on all
the R-Car gen3 SoCs except V3M (R8A77970) but the encoding of this field
is different between SoCs; it makes sense to support the most common case
of this encoding in the R-Car gen3 CPG driver...

After adding the RPCSRC clock, we can add the RPC[D2] clocks derived from
it and controlled by the RPCCKCR register on all the R-Car gen3 SoCs except
V3M (R8A77970); the composite clock driver seems handy for this task, using
the spinlock added in the previous patch...
