pinctrl: mediatek: support reading register base address by name

2025-02-10T16:26:47Z

This patch add support to read register base address by name if provided. Also devfdt_get_addr_* is changed to dev_read_addr_* to support DT live tree. Signed-off-by: Weijie Gao

pinctrl: mediatek: mt7988: remove _base from reg-names

2025-02-10T16:26:47Z

The reg-names in mt7988.dtsi have no _base suffix. Remove the suffix will also make it match upstream linux format. Fixes: 8c2cb748ef5 (pinctrl: mediatek: mt7988: rename reg-names to upstream linux format) Signed-off-by: Weijie Gao

Merge patch series "mediatek: final preparation for OF_UPSTREAM support"

2025-02-04T17:57:36Z

Christian Marangi says: This is the last batch of part to push actual support of OF_UPSTREAM for the mediatek SoC. The plan is to make the current downstream DTS on part with upstream implementation so we can permit a gradual transition to it while we don't cause any regression to any user. This is to have the same node downstream and upstream. Mediatek is working hard upstream to also push all the remaining nodes. All patch are the final changes after the pinctrl patch merged previously. All patch pass CI tests Link: https://github.com/u-boot/u-boot/pull/731 Link: https://lore.kernel.org/r/20250127134046.26345-1-ansuelsmth@gmail.com

pinctrl: mediatek: mt7981: rename reg-names to upstream linux format

Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"

2024-10-11T18:23:25Z

Simon Glass says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

drivers: Use CONFIG_XPL_BUILD instead of CONFIG_SPL_BUILD

pinctrl: mediatek: Bind gpio while binding pinctrl

2024-10-07T21:09:55Z

Mediatek pinctrl drivers call mtk_gpiochip_register() to bind the child gpio controller as part of mtk_pinctrl_common_probe(). This breaks gpiohog support because the gpio controller is bound too late for DM_FLAG_PROBE_AFTER_BIND (set while binding hogs) to work. Move the mtk_gpiochip_register() to mtk_pinctrl_common_bind() and call this as the .bind method of each of the mediatek pinctrl drivers. Signed-off-by: Chris Webb

pinctrl: mediatek: mt7981: init device before relocation

2024-07-08T17:45:50Z

Upstream kernel linux define pinctrl for uart0, hence this pin group and pinctrl driver is needed before relocation. Add DM_FLAG_PRE_RELOC flag to init and mute mtk_serial error on early serial init. Signed-off-by: Christian Marangi
