2021-06-10ARM: dts: stm32: Drop unused linux,wakeup from touchscreen node on DHCOM SoMMarek Vasut1-1/+0
Fix the following dtbs_check warning: touchscreen@38: 'linux,wakeup' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Marek Vasut <marex@denx.de> Cc: Alexandre Torgue <alexandre.torgue@foss.st.com> Cc: Patrice Chotard <patrice.chotard@foss.st.com> Cc: Patrick Delaunay <patrick.delaunay@foss.st.com> Cc: kernel@dh-electronics.com Cc: linux-stm32@st-md-mailman.stormreply.com To: linux-arm-kernel@lists.infradead.org Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>
2021-06-10ARM: dts: stm32: fix the Odyssey SoM eMMC VQMMC supplyGrzegorz Szymaszek1-1/+1
The Seeed SoM-STM32MP157C device tree had the eMMC’s (SDMMC2) VQMMC supply set to v3v3 (buck4), the same as the VMMC supply. That was incorrect, as on the SoM, the VQMMC supply is provided from vdd (buck3) instead.

2021-06-10ARM: dts: stm32: add a new DCMI pins group on stm32mp15Grzegorz Szymaszek1-0/+33
The Seeed Odyssey-STM32MP157C board has a 20-pin DVP camera output. stm32mp15-pinctrl.dtsi contained one pin state definition for the DCMI interface, dcmi-0, AKA phandle dcmi_pins_a. This definition was incompatible with the pins used on the Odyssey board, where: - there are 8 data pins instead of 12, - DCMI_HSYNC is available at PA4 instead of PH8, - DCMI_D0 is at PC6 instead of PH9, - DCMI_D3 is at PE1 instead of PH12, - DCMI_D4 is at PE11 instead of PH14, - DCMI_D5 is at PD3 instead of PI4, - DCMI_D6 is at PE13 instead of PB8, - DCMI_D7 is at PB9 instead of PE6. Add the DCMI pins used on the Odyssey board as a new DCMI pin state definition, dcmi-1, AKA phandle dcmi_pins_b.

2021-06-10genirq: Move non-irqdomain handle_domain_irq() handling into ARM's handle_IRQ()Marc Zyngier1-1/+21
Despite the name, handle_domain_irq() deals with non-irqdomain handling for the sake of a handful of legacy ARM platforms. Move such handling into ARM's handle_IRQ(), allowing for better code generation for everyone else. This allows us get rid of some complexity, and to rearrange the guards on the various helpers in a more logical way. Signed-off-by: Marc Zyngier <maz@kernel.org>

2021-06-08Revert "ARM: dts: bcm283x: increase dwc2's RX FIFO size"Stefan Wahren2-2/+2
This reverts commit 278407a53c3b33fb820332c4d39eb39316c3879a. The original change breaks USB config on Raspberry Pi Zero and Pi 4 B, because it exceeds the total fifo size of 4080. A naive attempt to reduce g-tx-fifo-size doesn't help on Raspberry Pi Zero. So better go back.

2021-06-07ARM: use a temporary variable to hold maximum vmalloc sizeRussell King (Oracle)1-2/+4
We calculate the maximum size of the vmalloc space twice in early_vmalloc(). Use a temporary variable to hold this value. Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Yanfei Xu <yanfei.xu@windriver.com> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
2021-06-07ARM: change vmalloc_min to be unsigned longRussell King (Oracle)1-4/+4
vmalloc_min is currently a void pointer, but everywhere its used contains a cast - either to a void pointer when setting or back to an integer type when being used. Eliminate these casts by changing its type to unsigned long.

2021-06-07ARM: update __swp_entry_to_pte() to use PTE_TYPE_FAULTRussell King (Oracle)1-1/+1
Swap entries use a faulting PTE which have the least two significant bits as zero. Due to this, the use of PTE_TYPE_FAULT was overlooked, but really should have been included in __swp_entry_to_pte(). Convert this macro to use PTE_TYPE_FAULT to properly document what is going on here, and use __pte() to convert the swp_entry_t to a pte_t. This results in no change to the resulting kernel image.
