ARM: davinci: remove support for da830

2025-04-16T16:02:20+00:00

We no longer support any boards with the da830 SoC in mainline linux.
Let's remove all bits and pieces related to it.

Pull irq driver updates from Thomas Gleixner:

 - Support for hard indices on RISC-V. The hart index identifies a hart
   (core) within a specific interrupt domain in RISC-V's Priviledged
   Architecture.

 - Rework of the RISC-V MSI driver

   This moves the driver over to the generic MSI library and solves the
   affinity problem of unmaskable PCI/MSI controllers. Unmaskable
   PCI/MSI controllers are prone to lose interrupts when the MSI message
   is updated to change the affinity because the message write consists
   of three 32-bit subsequent writes, which update address and data. As
   these writes are non-atomic versus the device raising an interrupt,
   the device can observe a half written update and issue an interrupt
   on the wrong vector. This is mitiated by a carefully orchestrated
   step by step update and the observation of an eventually pending
   interrupt on the CPU which issues the update. The algorithm follows
   the well established method of the X86 MSI driver.

 - A new driver for the RISC-V Sophgo SG2042 MSI controller

 - Overhaul of the Renesas RZQ2L driver

   Simplification of the probe function by using devm_*() mechanisms,
   which avoid the endless list of error prone gotos in the failure
   paths.

 - Expand the Renesas RZV2H driver to support RZ/G3E SoCs

 - A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to
   ensure that the addressing is limited to the lower 32-bit of the
   physical address space.

 - Add support for the Allwinner AS23 NMI controller

 - Expand the IMX irqsteer driver to handle up to 960 input interrupts

 - The usual small updates, cleanups and device tree changes

ARM: davinci: always enable CONFIG_ARCH_DAVINCI_DA850

2025-03-24T21:34:37+00:00

A change to the clk driver broke configurations that enable DA830
but not DA850:

arm-linux-gnueabi-ld: drivers/clk/davinci/pll.o: in function `__da850_pll0_of_clk_init_declare':
pll.c:(.init.text+0x30): undefined reference to `of_da850_pll0_init'

arm-linux-gnueabi-ld: drivers/clk/davinci/pll.o:(.rodata.davinci_pll_id_table+0x2c): undefined reference to `da850_pll1_init'
arm-linux-gnueabi-ld: drivers/clk/davinci/pll.o:(.rodata.davinci_pll_of_match+0xc0): undefined reference to `of_da850_pll1_init'

arm-linux-gnueabi-ld: drivers/clk/davinci/psc.o:(.rodata.davinci_psc_id_table+0x2c): undefined reference to `da850_psc1_init_data'

Select ARCH_DAVINCI_DA850 unconditionally to ensure the driver can still
build.

ARM: davinci: da850: fix selecting ARCH_DAVINCI_DA8XX

2025-03-14T17:24:05+00:00

Chips in the DA850 family need to have ARCH_DAVINCI_DA8XX to be selected
in order to enable some peripheral drivers.

This was accidentally removed in a previous commit.

irqchip/davinci-cp-intc: Remove public header

2025-03-04T14:46:59+00:00

There are no more users of irq-davinci-cp-intc.h (da830.c doesn't use
any of its symbols). Remove the header and make the driver stop using the
config structure.
