serial: 8250: Move CE4100 quirks to a module under 8250 driver

2025-06-29T12:24:46Z

There is inconvenient for maintainers and maintainership to have some quirks under architectural code. Move it to the specific quirk file like other 8250-compatible drivers do.

serial: ce4100: clean up serial_in/out() hooks

2025-06-24T14:32:50Z

ce4100_mem_serial_in() unnecessarily contains 4 nested 'if's. That makes the code hard to follow. Invert the conditions and return early if the particular conditions do not hold. And use "<<=" for shifting the offset in both of the hooks. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Borislav Petkov Cc: Dave Hansen Cc: x86@kernel.org Cc: "H.

serial: ce4100: fix build after serial_in/out() changes

2025-06-24T14:32:50Z

This x86_32 driver remain unnoticed, so after the commit below, the compilation now fails with: arch/x86/platform/ce4100/ce4100.c:107:16: error: incompatible function pointer types assigning to '...' from '...' To fix the error, convert also ce4100 to the new uart_port::serial_{in,out}() types.

x86/of: Set the parse_smp_cfg for all the DeviceTree platforms by default

2024-04-03T06:46:08Z

x86_dtb_parse_smp_config() must be set by DeviceTree platform for parsing SMP configuration. Set the parse_smp_cfg pointer to x86_dtb_parse_smp_config() by default so that all the dtb platforms need not to assign it explicitly. Today there are only two platforms using DeviceTree in x86, ce4100 and hv_vtl. Remove the explicit assignment of x86_dtb_parse_smp_config() function from these.

x86/mpparse: Switch to new init callbacks

2024-02-15T21:07:41Z

Now that all platforms have the new split SMP configuration callbacks set up, flip the switch and remove the old callback pointer and mop up the platform code.

x86/mpparse: Rename default_find_smp_config()

MPTABLE is no longer the default SMP configuration mechanism. Rename it to mpparse_find_mptable() because that's what it does. Signed-off-by: Thomas Gleixner Tested-by: Michael Kelley Tested-by: Sohil Mehta Link: https://lore.kernel.org/r/20240212154639.306287711@linutronix.de

There is no point to do that. The ATOMs have an XAPIC for which this function is a pointless exercise. Signed-off-by: Thomas Gleixner Tested-by: Michael Kelley Tested-by: Sohil Mehta Link: https://lore.kernel.org/r/20240212154638.931617775@linutronix.de

x86/ce4100: Replace "ti,pcf8575" by "nxp,pcf8575"

2021-12-03T17:23:57Z

The TI part is equivalent to the NXP part, and its compatible value is not documented in the DT bindings. Note that while the Linux driver DT match table does not contain the compatible value of the TI part, it could still match to this part, as i2c_device_id-based matching ignores the vendor part of the compatible value.
