#1438989 — [PATCH v2 0/6] Add clock support for Armada 37xx SoCs

Hi,

eventually this is the second version of the series adding clock
support for the Armada 37xx SoCs.

The design of the drivers is as close as possible as the hardware is,
with some clocks made of several layers: muxing, divider and gating.

The device tree binding was written in a way that even if we discover
some change inside the clocks, the binding should not be
affected. Especially, there are some holes in the clocks, but we
should be able to add them seamless.

Since the firs version the main change is the use of clk_hw instead of
clk for the registration. I also removed the dt related patches as they
were already applied.

However the full series is available on the branch
Armada-3700-Clocks-v2 at
git@github.com:MISL-EBU-System-SW/mainline-public.git

Thanks,

Changelog:

v1 -> v2

- Move to clk_hw based registration for the 3 clock driver as
  requested by Stephen Boyd
- Fixed typo noticed by Stephen Boyd
- Added const and static when they were missing: suggested by Stephen
  Boyd
- Allocated the driver variable during probe instead of using a global
  one as requested by Stephen Boyd
- Managed the failure of the of_clk_add_hw_provider call
- Added the Acked-by from Rob Herring on the dt binding patchs

+* Peripheral Clock bindings for Marvell Armada 37xx SoCs
+
+Marvell Armada 37xx SoCs provide peripheral clocks which are
+used as clock source for the peripheral of the SoC.
+
+There are two different blocks associated to north bridge and south
+bridge.
+
+The peripheral clock consumer should specify the desired clock by
+having the clock ID in its "clocks" phandle cell.
+
+The following is a list of provided IDs for Armada 370 North bridge clocks:
+ID	Clock name	Description
+-----------------------------------
+0	mmc		MMC controller
+1	sata_host	Sata Host
+2	sec_at		Security AT
+3	sac_dap		Security DAP
+4	tsecm		Security Engine
+5	setm_tmx	Serial Embedded Trace Module
+6	avs		Adaptive Voltage Scaling
+7	sqf		SPI
+8	pwm		PWM
+9	i2c_2		I2C 2
+10	i2c_1		I2C 1
+11	ddr_phy		DDR PHY
+12	ddr_fclk	DDR F clock
+13	trace		Trace
+14	counter		Counter
+15	eip97		EIP 97
+16	cpu		CPU
+
+The following is a list of provided IDs for Armada 370 South bridge clocks:
+ID	Clock name	Description
+-----------------------------------
+0	gbe-50		50 MHz parent clock for Gigabit Ethernet
+1	gbe-core	parent clock for Gigabit Ethernet core
+2	gbe-125		125 MHz parent clock for Gigabit Ethernet
+3	gbe1-50		50 MHz clock for Gigabit Ethernet port 1
+4	gbe0-50		50 MHz clock for Gigabit Ethernet port 0
+5	gbe1-125	125 MHz clock for Gigabit Ethernet port 1
+6	gbe0-125	125 MHz clock for Gigabit Ethernet port 0
+7	gbe1-core	Gigabit Ethernet core port 1
+8	gbe0-core	Gigabit Ethernet core port 0
+9	gbe-bm		Gigabit Ethernet Buffer Manager
+10	sdio		SDIO
+11	usb32-sub2-sys	USB 2 clock
+12	usb32-ss-sys	USB 3 clock
+
+Required properties:
+
+- compatible : shall be "marvell,armada-3700-periph-clock-nb" for the
+  north bridge block, or
+  "marvell,armada-3700-periph-clock-sb" for the south bridge block
+- reg : must be the register address of North/South Bridge Clock register
+- #clock-cells : from common clock binding; shall be set to 1
+
+- clocks : list of the parent clock phandle in the following order:
+  TBG-A P, TBG-B P, TBG-A S, TBG-B S and finally the xtal clock.
+
+
+Example:
+
+nb_perih_clk: nb-periph-clk@13000{
+	compatible = "marvell,armada-3700-periph-clock-nb";
+	reg = <0x13000 0x1000>;
+	clocks = <&tbg 0>, <&tbg 1>, <&tbg 2>,
+	<&tbg 3>, <&xtalclk>;
+	#clock-cells = <1>;
+};
