2025-12-01gpio: dwapb: Enable SPL support for DWAPB GPIO driverTanmay Kathpalia
Add SPL_DWAPB_GPIO configuration option to enable the Designware APB GPIO driver in SPL builds. Changes: - Add SPL_DWAPB_GPIO Kconfig option with SPL_DM_GPIO dependency - Update Makefile to use CONFIG_$(PHASE_)DWAPB_GPIO pattern for conditional compilation in both SPL and main U-Boot builds Signed-off-by: Tanmay Kathpalia <tanmay.kathpalia@altera.com> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Tom Rini <trini@konsulko.com>

2025-07-14gpio: qcom: add new driver for SPMI gpiosNeil Armstrong
The current qcom_pmic_gpio driver is too limited and doesn't support state tracking for all pins like the Linux driver. Adding full pinconf support would require adding the state and it's much simpler to restart from scratch with a new driver based on the Linux one adapted to the U-Boot GPIO and Pinctrl APIs. For now only the PMICs I've been able to validate are added in the compatible list but we should be able to add the entire list from the Linux driver. There's a few difference from the Linux driver: - no IRQ support - uses the U-Boot GPIO flags that maps very well - uses the gpio-ranges to get the pins count - no debugfs but prints the pin state via pinmux callback It uses the same CONFIG entry as the old one, since the ultimate goal is to migrate entirely on this new driver once we verify it doesn't break the older platforms.

2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <sjg@chromium.org> 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.
