Use the new renesas-ceu camera driver is ms7724se board file instead of the soc_camera based sh_mobile_ceu_camera driver. Get rid of soc_camera specific components, and register CEU0 and CEU1 with no active video subdevices. Memory for the CEU video buffers is now reserved with membocks APIs and need to be declared as dma_coherent during machine initialization to remove that architecture specific part from CEU driver. While at there update license to SPDX header and sort headers alphabetically. No need to udapte the clock source names, as commit c2f9b05f ("media: arch: sh: ecovec: Use new renesas-ceu camera driver") already updated it to the new ceu driver name for all SH7724 boards (possibly breaking ms7724se before this commit).

Remove soc_camera framework dependencies from rj54n1 sensor driver. - Handle clock - Handle GPIOs (named 'powerup' and 'enable') - Register the async subdevice - Remove g/s_mbus_config as they're deprecated. - Adjust build system - List the driver as maintained for 'Odd Fixes' as I don't have HW to test. This commits does not remove the original soc_camera based driver. Compiled tested only.

Niklas Söderlund authored
When starting the VIN capture procedure we are not guaranteed that the first buffer written to is VnMB1 to which we assigned the first buffer queued. This is problematic for two reasons. Buffers might not be dequeued in the same order they where queued for capture. Future features planed for the VIN driver is support for outputting frames in SEQ_TB/BT format and to do that it's important that capture starts from the first buffer slot, VnMB1. We are guaranteed that capturing always happens in sequence (VnMB1 -> VnMB2 -> VnMB3 -> VnMB1). So drop up to two frames when starting capturing so that the driver always returns buffers in the same order they are queued and prepare for SEQ_TB/BT output.

The Renesas Fine Display Processor driver is used on Renesas R-Car SoCs only. Since commit 9b5ba0df ("ARM: shmobile: Introduce ARCH_RENESAS") is ARCH_RENESAS a more appropriate platform dependency than the legacy ARCH_SHMOBILE, hence use the former. This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near future.

The following commit: 2c3625cb ("efi/x86: Fold __setup_efi_pci32() and __setup_efi_pci64() into one function") ... merged the two versions of __setup_efi_pciXX(), without taking into account that the 32-bit version used a rather dodgy trick to pass an immediate 0 constant as argument for a uint64_t parameter. The issue is caused by the fact that on x86, UEFI protocol method calls are redirected via struct efi_config::call(), which is a variadic function, and so the compiler has to infer the types of the parameters from the arguments rather than from the prototype. As the 32-bit x86 calling convention passes arguments via the stack, passing the unqualified constant 0 twice is the same as passing 0ULL, which is why the 32-bit code in __setup_efi_pci32() contained the following call: status = efi_early->call(pci->attributes, pci, EfiPciIoAttributeOperationGet, 0, 0, &attributes); to invoke this UEFI protocol method: typedef EFI_STATUS (EFIAPI *EFI_PCI_IO_PROTOCOL_ATTRIBUTES) ( IN EFI_PCI_IO_PROTOCOL *This, IN EFI_PCI_IO_PROTOCOL_ATTRIBUTE_OPERATION Operation, IN UINT64 Attributes, OUT UINT64 *Result OPTIONAL ); After the merge, we inadvertently ended up with this version for both 32-bit and 64-bit builds, breaking the latter. So replace the two zeroes with the explicitly typed constant 0ULL, which works as expected on both 32-bit and 64-bit builds. Wilfried tested the 64-bit build, and I checked the generated assembly of a 32-bit build with and without this patch, and they are identical.
