[U-Boot] [PATCH 1/2] dm: Tidy up dump output when there are many devices
At present the 'Index' column of 'dm tree' assumes there is two digits, this patch increase it to 3 digits.
It also aligns output of 'dm uclass', assuming the same 3 digits index.
The boards with CONFIG_PINCTRL_FULL activated have one pinconfig by pin configuration, so they can have more than 100 devices pinconfig (for example with stm32mp157c-ev1 board we have 106 pinconfig node).

In the Linux pinctrl binding, the pin configuration nodes don't need to be direct children of the pin controller device (may be grandchildren for example). This behavior is managed with the pinconfig u-class which recursively bind all the sub-node of the pin controller.
But for some binding (when pin configuration is only children of pin controller) that is not necessary. U-Boot can save memory and reduce the number of pinconf instance when this feature is deactivated (for arch stm32mp for example for SPL).
This patch allows to control this feature with a new option CONFIG_PINCONF_RECURSIVE when it is possible for each individual pin controller device.
Hi,
Found her a proposal to have a more clear output of "dm tree" command and to reduce the memory footprint of PINCTRL_FULL for the arch stm32mp1 (bdinfo "Early malloc usage" is reduced from 2588 to 2144).
On stm32mp157c-ev1, each pin configuration have one other several sub node "pins"
pinctrl: pin-controller@50002000 { ... adc12_usb_pwr_pins_a: adc12-usb-pwr-pins-0 { pins { pinmux = <STM32_PINMUX('A', 4, ANALOG)>, /* ADC12 in18 */ <STM32_PINMUX('A', 5, ANALOG)>; /* ADC12 in19 */ }; };
cec_pins_a: cec-0 { pins { pinmux = <STM32_PINMUX('A', 15, AF4)>; bias-disable; drive-open-drain; slew-rate = <0>; }; };
cec_pins_sleep_a: cec-sleep-0 { pins { pinmux = <STM32_PINMUX('A', 15, ANALOG)>; /* HDMI_CEC */ }; }; ... ethernet0_rgmii_pins_a: rgmii-0 { pins1 { pinmux = <STM32_PINMUX('G', 5, AF11)>, /* ETH_RGMII_CLK125 */ <STM32_PINMUX('G', 4, AF11)>, /* ETH_RGMII_GTX_CLK */ <STM32_PINMUX('G', 13, AF11)>, /* ETH_RGMII_TXD0 */ <STM32_PINMUX('G', 14, AF11)>, /* ETH_RGMII_TXD1 */ <STM32_PINMUX('C', 2, AF11)>, /* ETH_RGMII_TXD2 */ <STM32_PINMUX('E', 2, AF11)>, /* ETH_RGMII_TXD3 */ <STM32_PINMUX('B', 11, AF11)>, /* ETH_RGMII_TX_CTL */ <STM32_PINMUX('C', 1, AF11)>; /* ETH_MDC */ bias-disable; drive-push-pull; slew-rate = <2>; }; pins2 { pinmux = <STM32_PINMUX('A', 2, AF11)>; /* ETH_MDIO */ bias-disable; drive-push-pull; slew-rate = <0>; }; pins3 { pinmux = <STM32_PINMUX('C', 4, AF11)>, /* ETH_RGMII_RXD0 */ <STM32_PINMUX('C', 5, AF11)>, /* ETH_RGMII_RXD1 */ <STM32_PINMUX('B', 0, AF11)>, /* ETH_RGMII_RXD2 */ <STM32_PINMUX('B', 1, AF11)>, /* ETH_RGMII_RXD3 */ <STM32_PINMUX('A', 1, AF11)>, /* ETH_RGMII_RX_CLK */ <STM32_PINMUX('A', 7, AF11)>; /* ETH_RGMII_RX_CTL */ bias-disable; }; }; ...
before the patch all "pins" subnode are bounded but are unused.

Hi,
From: Patrick DELAUNAY patrick.delaunay@st.com Sent: jeudi 1 août 2019 11:23 Subject: [PATCH 2/2] dm: pinctrl: introduce PINCONF_RECURSIVE option Importance: High
In the Linux pinctrl binding, the pin configuration nodes don't need to be direct children of the pin controller device (may be grandchildren for example). This behavior is managed with the pinconfig u-class which recursively bind all the sub- node of the pin controller.
But for some binding (when pin configuration is only children of pin controller) that is not necessary. U-Boot can save memory and reduce the number of pinconf instance when this feature is deactivated (for arch stm32mp for example for SPL).
This patch allows to control this feature with a new option CONFIG_PINCONF_RECURSIVE when it is possible for each individual pin controller device.
I resent the patch will correct commit message and commit notes
("Commit-note:" => "Commit-notes": for patman)

Sorry for disturbance.

Hi,
Found her a proposal to have a more clear output of "dm tree" command and to reduce the memory footprint of PINCTRL_FULL for the arch stm32mp1 (bdinfo "Early malloc usage" is reduced from 2588 to 2144).
On stm32mp157c-ev1, each pin configuration have one other several sub node "pins"
pinctrl: pin-controller@50002000 { ... adc12_usb_pwr_pins_a: adc12-usb-pwr-pins-0 { pins { pinmux = <STM32_PINMUX('A', 4, ANALOG)>, /* ADC12 in18 */ <STM32_PINMUX('A', 5, ANALOG)>; /* ADC12 in19 */ }; };
cec_pins_a: cec-0 { pins { pinmux = <STM32_PINMUX('A', 15, AF4)>; bias-disable; drive-open-drain; slew-rate = <0>; }; };
cec_pins_sleep_a: cec-sleep-0 { pins { pinmux = <STM32_PINMUX('A', 15, ANALOG)>; /* HDMI_CEC */ }; }; ... ethernet0_rgmii_pins_a: rgmii-0 { pins1 { pinmux = <STM32_PINMUX('G', 5, AF11)>, /* ETH_RGMII_CLK125 */ <STM32_PINMUX('G', 4, AF11)>, /* ETH_RGMII_GTX_CLK */ <STM32_PINMUX('G', 13, AF11)>, /* ETH_RGMII_TXD0 */ <STM32_PINMUX('G', 14, AF11)>, /* ETH_RGMII_TXD1 */ <STM32_PINMUX('C', 2, AF11)>, /* ETH_RGMII_TXD2 */ <STM32_PINMUX('E', 2, AF11)>, /* ETH_RGMII_TXD3 */ <STM32_PINMUX('B', 11, AF11)>, /* ETH_RGMII_TX_CTL */ <STM32_PINMUX('C', 1, AF11)>; /* ETH_MDC */ bias-disable; drive-push-pull; slew-rate = <2>; }; pins2 { pinmux = <STM32_PINMUX('A', 2, AF11)>; /* ETH_MDIO */ bias-disable; drive-push-pull; slew-rate = <0>; }; pins3 { pinmux = <STM32_PINMUX('C', 4, AF11)>, /* ETH_RGMII_RXD0 */ <STM32_PINMUX('C', 5, AF11)>, /* ETH_RGMII_RXD1 */ <STM32_PINMUX('B', 0, AF11)>, /* ETH_RGMII_RXD2 */ <STM32_PINMUX('B', 1, AF11)>, /* ETH_RGMII_RXD3 */ <STM32_PINMUX('A', 1, AF11)>, /* ETH_RGMII_RX_CLK */ <STM32_PINMUX('A', 7, AF11)>; /* ETH_RGMII_RX_CTL */ bias-disable; }; }; ...
before the patch all "pins" subnode are bounded but are unused.

In the Linux pinctrl binding, the pin configuration nodes need not bedirect children of the pin controller device (may be grandchildren forexample). It is define is each individual pin controller device.Say Y here if you want to keep this behavior with the pinconfigu-class: all sub are recursivelly bounded.If the option is disabled, this behavior is deactivated and onlythe direct children of pin controller will be assumed as pinconfiguration; you can save memory footprint when this feature isno needed.config SPL_PINCTRL bool "Support pin controllers in SPL" depends on SPL && SPL_DM @@ -104,6 +120,15 @@ config SPL_PINCONF This option is an SPL-variant of the PINCONF option.

Hi Patrick,

At present the 'Index' column of 'dm tree' assumes there is two digits, this patch increase it to 3 digits.
It also aligns output of 'dm uclass', assuming the same 3 digits index.
The boards with CONFIG_PINCTRL_FULL activated have one pinconfig by pin configuration, so they can have more than 100 devices pinconfig (for example with stm32mp157c-ev1 board we have 106 pinconfig node).

But please do check that this does not break 'make qcheck' as I thought there were tests for this?
