Every device on a SCU based system has a resource id. Exported it in device tree to allow service bindings to use it. e.g. power domain.

3501ce96bf5d9dd8563dd94595436d3757ec817e Mon Sep 17 00:00:00 2001 From: "A.s. Dong" Date: Thu, 1 Nov 2018 15:19:58 +0000 Subject: [PATCH 03/33] firmware: imx: remove resource id enums We already export resource id in dt-bindings headfile which can also be used by drivers. So no need keep the same definitions in regular headfile anymore.

The first cell can be a global SCU power domain and the 2nd cell the device ID. With this approach, we may remove all the sub power domain nodes from device tree which can relief the device tree a lot.

d3ff9728134eeaa13d5bbb23c3f2e188f99cfdf9 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Sat, 1 Dec 2018 10:52:14 +0000 Subject: [PATCH 07/33] clk: imx: Add imx composite clock Since a lot of clocks on imx8m are formed by a mux, gate, predivider and divider, the idea here is to combine all of those into one composite clock, but we need to deal with both predivider and divider at the same time and therefore we add the imx8m_clk_composite_divider_ops and register the composite clock with those.

Dong" Date: Wed, 14 Nov 2018 13:01:35 +0000 Subject: [PATCH 11/33] clk: imx: add gatable clock divider support For dividers with zero indicating clock is disabled, instead of giving a warning each time like "clkx: Zero divisor and CLK_DIVIDER_ALLOW_ZERO not set" in exist code, we'd like to introduce enable/disable function for it. e.g. 000b - Clock disabled 001b - Divide by 1 010b - Divide by 2 ... Set rate when the clk is disabled will cache the rate request and only when the clk is enabled will the driver actually program the hardware to have the requested divider value. Similarly, when the clk is disabled we'll write a 0 there, but when the clk is enabled we'll restore whatever rate (divider) was chosen last. It does mean that recalc rate will be sort of odd, because when the clk is off it will return 0, and when the clk is on it will return the right rate. So to make things work, we'll need to return the cached rate in recalc rate when the clk is off and read the hardware when the clk is on. NOTE for the default off divider, the recalc rate will still return 0 as there's still no proper preset rate. Enable such divider will give user a reminder error message.

Dong" Date: Wed, 14 Nov 2018 13:02:08 +0000 Subject: [PATCH 19/33] clk: imx: add imx7ulp clk driver i.MX7ULP Clock functions are under joint control of the System Clock Generation (SCG) modules, Peripheral Clock Control (PCC) modules, and Core Mode Controller (CMC)1 blocks The clocking scheme provides clear separation between M4 domain and A7 domain. Except for a few clock sources shared between two domains, such as the System Oscillator clock, the Slow IRC (SIRC), and and the Fast IRC clock (FIRCLK), clock sources and clock management are separated and contained within each domain. M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules. A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules. This driver only adds clock support in A7 domain. Note that most clocks required to be operated when gated, e.g. pll, pfd, pcc. And more special cases that scs/ddr/nic mux selecting different clock source requires that clock to be enabled first, then we need set CLK_OPS_PARENT_ENABLE flag for them properly.

This is in line with how drivers of the later CCM driver revisions on newer i.MX SoCs handle this.

The hardware setup looks something like this: _ refclk-o---PLL---o----DIV1-----| \ | | |M |----OUT1 o-----------------------|_/ | | _ | o----DIV2-----| \ | | |M |----OUT2 o-----------------------|_/ | | _ | `----DIV3-----| \ | |M |----OUT3 `-----------------------|_/ The bypass bit not only bypasses the PLL, but also the attached post-dividers. This would be reasonbly straight forward to model with a single output, or with different bypass bits for each output, but sadly the HW guys decided that it would be good to actuate all 3 muxes with a single bit. So the need to have the PLL bypassed for one of the outputs always affects 2 other (in our model) independent branches of the clock tree. This means the decision to bypass this PLL is a system wide design choice and should not be changed on-the-fly, so we can treat any bapass configuration as static. As such we can just register the post-dividiers with a ratio that reflects the bypass status, which allows us to bypass the PLL without breaking our abstraction model and with it DT stability.
