pinctrl: meson: meson8b: add the GPIOH pinmux settings for ETH_RXD{2,3}

2020-01-07T12:57:17+00:00

GPIOH_5 and GPIOH_6 can have two Ethernet related functions: - GPIOH_5 can be ETH_TXD1 or ETH_RXD3 - GPIOH_6 can be ETH_TXD0 or ETH_RXD2 Add the bits for eth_rxd3_h and eth_rxd2_h so the ETH_RXD function can be disabled when using the ETH_TXD function of GPIOH_{5,6}. No problem was observed so far, but in theory this could lead to two different signals being routed to the same pad (which could break Ethernet).

pinctrl: meson: Fix wrong shift value when get drive-strength

2020-01-07T10:21:07+00:00

In meson_pinconf_get_drive_strength, variable bit is calculated by meson_calc_reg_and_bit, this value is the offset from the first pin of a certain bank to current pin, while Meson SoCs use two bits for each pin to depict drive-strength. So a left shift by 1 should be done or node pinconf-pins shows wrong message.

pinctrl: meson: add pinctrl driver support for Meson-A1 SoC

2019-11-19T14:55:26+00:00

Meson A1 SoC share the same register layout of pinmux with previous Meson-G12A, however there is difference for gpio and pin config register in A1. The main difference is that registers before A1 are grouped by function while those of A1 are by bank. The new register layout is as below: /* first bank */ /* addr */ - P_PADCTRL_GPIOP_I base + 0x00 << 2 - P_PADCTRL_GPIOP_O base + 0x01 << 2 - P_PADCTRL_GPIOP_OEN base + 0x02 << 2 - P_PADCTRL_GPIOP_PULL_EN base + 0x03 << 2 - P_PADCTRL_GPIOP_PULL_UP base + 0x04 << 2 - P_PADCTRL_GPIOP_DS base + 0x05 << 2 /* second bank */ - P_PADCTRL_GPIOB_I base + 0x10 << 2 - P_PADCTRL_GPIOB_O base + 0x11 << 2 - P_PADCTRL_GPIOB_OEN base + 0x12 << 2 - P_PADCTRL_GPIOB_PULL_EN base + 0x13 << 2 - P_PADCTRL_GPIOB_PULL_UP base + 0x14 << 2 - P_PADCTRL_GPIOB_DS base + 0x15 << 2 Each bank contains at least 6 registers to be configured, if one bank has more than 16 gpios, an extra P_PADCTRL_GPIO[X]_DS_EXT is included. Between two adjacent P_PADCTRL_GPIO[X]_I, there is an offset 0x10, that is to say, for third bank, the offsets will be 0x20,0x21,0x22,0x23,0x24 ,0x25 according to above register layout. For previous chips, registers are grouped according to their functions while registers of A1 are according to bank.Also note that there is no AO bank any more in A1. Current Meson pinctrl driver can cover such change by using base address of GPIO as that of drive-strength. While simply giving reg_ds = reg_pullen make wrong value to reg_ds for Socs that do not support drive-strength like AXG.To make things simple, add an extra dt parser function for a1 and remain the old dt parser function for only reg parsing.

pinctrl: meson-gxbb: Fix wrong pinning definition for uart_c

2019-09-13T12:40:41+00:00

Hi i tried to use the uart_C of the the odroid-c2. I enabled it in the dts file. During boot it crashed when the the sdcard slot is addressed. After long search in the net i found this: https://forum.odroid.com/viewtopic.php?f=139&t=25371&p=194370&hilit=uart_C#p177856 After changing the pin definitions accordingly erverything works. Uart_c is functioning and sdcard ist working.

pinctrl: meson: meson: Add of_node_put() before return

2019-08-23T09:48:08+00:00

Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return. Issue found with Coccinelle.

2019-07-13T22:02:27+00:00

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...
