Subject: [rfc, PATCH v1 0/7] PCI: introduce p2sb helper
Date: Mon, 8 Mar 2021 14:20:13 +0200 [thread overview]
Message-ID: <20210308122020.57071-1-andriy.shevchenko@linux.intel.com> (raw)
There are a few users and even at least one more is coming
that would like to utilize p2sb mechanisms like hide/unhide
a device from PCI configuration space.
Here is the series to deduplicate existing users and provide
a generic way for new comers.
It also includes a patch to enable GPIO controllers on Apollo Lake
when it's used with ABL bootloader w/o ACPI support.
Please, comment on the approach and individual patches.
(Since it's cross subsystem, the PCI seems like a main one and
I think it makes sense to route it thru it with immutable tag
or branch provided for the others).
Andy Shevchenko (5):
PCI: Introduce pci_bus_*() printing macros when device is not
available
PCI: Convert __pci_read_base() to __pci_bus_read_base()
mfd: lpc_ich: Factor out lpc_ich_enable_spi_write()
mfd: lpc_ich: Switch to generic pci_p2sb_bar()
i2c: i801: convert to use common P2SB accessor
Jonathan Yong (1):
PCI: New Primary to Sideband (P2SB) bridge support library
Tan Jui Nee (1):
mfd: lpc_ich: Add support for pinctrl in non-ACPI system
