2023-08-02powerpc: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-03-16powerpc: Make generic_calibrate_decr() the defaultChristophe Leroy
ppc_md.calibrate_decr() is a mandatory item. Its nullity is never checked so it must be non null on all platforms. Most platforms define generic_calibrate_decr() as their ppc_md.calibrate_decr(). Have time_init() call generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL, and remove default assignment from all machines.

2023-03-11powerpc/83xx/mpc832x_rdb: Replace all spi->chip_select references with ↵Amit Kumar Mahapatra
function call Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

2019-12-09soc: fsl: qe: move calls of qe_ic_init out of arch/powerpc/Rasmus Villemoes
Having to call qe_ic_init() from platform-specific code makes it awkward to allow building the QE drivers for ARM. It's also a needless duplication of code, and slightly error-prone: Instead of the caller needing to know the details of whether the QUICC Engine High and QUICC Engine Low are actually the same interrupt (see e.g. the machine_is() in mpc85xx_mds_qeic_init), just let the init function choose the appropriate handlers after it has parsed the DT and figured it out. If the two interrupts are distinct, use separate handlers, otherwise use the handler which first checks the CHIVEC register (for the high priority interrupts), then the CIVEC. All existing callers pass 0 for flags, so continue to do that from the new single caller. Later cleanups will remove that argument from qe_ic_init and simplify the body, as well as make qe_ic_init into a proper init function for an IRQCHIP_DECLARE, eliminating the need to manually look up the fsl,qe-ic node.

2016-09-20powerpc: Remove all usages of NO_IRQMichael Ellerman
NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches. Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem. So we'd like to remove it. This is fairly trivial in the arch code, we just convert: if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0; And a few other odd cases as well. At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees. Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2016-07-21powerpc: Move 32-bit probe() machine to later in the boot processBenjamin Herrenschmidt

Unlike 64-bit, the 32-bit kernel didn't rely on platform initializations to setup the MMU since it sets it up entirely before probe_machine() so the move has comparatively less consequences though it's a bigger patch.

2007-10-08[POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascadingAnton Vorontsov
set_irq_chained_handler overwrites MPIC's handle_irq function (handle_fasteoi_irq) thus MPIC never gets eoi event from the cascaded IRQ. This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.

2007-10-08[POWERPC] Use for_each_ matching routinues for pci PHBsKumar Gala
On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete bridges (mpc10x, tsi108) use the new for_each_compatible_node() or for_each_node_by_type() to provide more exact matching when looking for PHBs in the device tree. With the previous code it was possible to match on pci bridges since we were only matching on device_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-14[POWERPC] MPC832x_RDB: Update dts to use SPI1 in QE, register mmc_spi stubAnton Vorontsov
Enabled using SPI controller on the MPC832x RDB board. We currently use a modalias of "spidev" as a place holder (replace with "mmc_spie") until the mmc_spi driver support is merged in. This gets us the ability to test SPI until then. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-14[POWERPC] 83xx: Removed PCI exclude of PHBKumar Gala
Now that the generic code doesn't assign resources for Freescale PHBs we dont have to explicitly exclude it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-08-10[POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms ↵Kim Phillips
with QE UEC" This reverts commit 3baee955953957be5496cd28e9c544d9db214262. That commit was a mistake from the start; I added mdio type to the bus scan list early on in my ucc_geth migrate to phylib development, which is just pure wrong (the ucc_geth_mii driver creates the mii bus and the PHY layer handles PHY enumeration without translation). This follows on from commit 77926826f301fbd8ed96d3cd9ff17a5b59560dfb: Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()" which was basically trying to hide a symptom of the original mistake this revert fixes.

2007-06-29[POWERPC] kill isa_{io,mem}_base definitions for !PCIArnd Bergmann
When CONFIG_PCI is disabled, the definitions for isa_io_base, isa_mem_base and pci_dram_offset are entirely unused, but they can result in link failure because they are defined in multiple places. The easiest fix is to just remove all these definitions. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-06-29[POWERPC] rename add_bridge to avoid namespace clashesArnd Bergmann
Many platforms currently define their own add_bridge function, some of them globally. This breaks some multiplatform configurations. Prefixing each of these functions with the platform name avoids this problem. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2007-05-02[POWERPC] Add 'mdio' to bus scan id list for platforms with QE UECKim Phillips
Add 'mdio' to bus scan id list for platforms with QE UEC as a consequence of converting UEC mdio driver to an of_platform driver in the ucc_geth phylib conversion patch. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
