Support for the Exynos4212 SoC was originally dropped as there were
no boards using it. We will be adding a device that uses it, so add
it back.

This reverts commit fee7e1d50c6e6da1d99035181ba5a5c88f5bb526.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Consolidate duplicated 'next function' scanning and extend to allow
     'isolated functions' on s390, similar to existing hypervisors
     (Niklas Schnelle)

  Resource management:
   - Implement pci_iobar_pfn() for sparc, which allows us to remove the
     sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().

     This removes the ability to map the entire PCI I/O space using
     /proc/bus/pci, but we believe that's already been broken since
     v2.6.28 (Arnd Bergmann)

   - Move common PCI definitions to asm-generic/pci.h and rework others
     to be be more specific and more encapsulated in arches that need
     them (Stafford Horne)

  Power management:

   - Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef
     CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)

  Virtualization:

   - Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate
     the functions but don't advertise an ACS capability (Pavan Chebbi)

  Error handling:

   - Clear PCI Status register during enumeration in case firmware left
     errors logged (Kai-Heng Feng)

   - When we have native control of AER, enable error reporting for all
     devices that support AER. Previously only a few drivers enabled
     this (Stefan Roese)

   - Keep AER error reporting enabled for switches. Previously we
     enabled this during enumeration but immediately disabled it (Stefan
     Roese)

   - Iterate over error counters instead of error strings to avoid
     printing junk in AER sysfs counters (Mohamed Khalfella)

  ASPM:

   - Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g.,
     via sysfs, are not lost across power state changes (Kai-Heng Feng)

  Endpoint framework:

   - Don't stop an EPC when unbinding an EPF from it (Shunsuke Mie)

  Endpoint embedded DMA controller driver:

   - Simplify and clean up support for the DesignWare embedded DMA
     (eDMA) controller (Frank Li, Serge Semin)

  Broadcom STB PCIe controller driver:

   - Avoid config space accesses when link is down because we can't
     recover from the CPU aborts these cause (Jim Quinlan)

   - Look for power regulators described under Root Ports in DT and
     enable them before scanning the secondary bus (Jim Quinlan)

   - Disable/enable regulators in suspend/resume (Jim Quinlan)

  Freescale i.MX6 PCIe controller driver:

   - Simplify and clean up clock and PHY management (Richard Zhu)

   - Disable/enable regulators in suspend/resume (Richard Zhu)

   - Set PCIE_DBI_RO_WR_EN before writing DBI registers (Richard Zhu)

   - Allow speeds faster than Gen2 (Richard Zhu)

   - Make link being down a non-fatal error so controller probe doesn't
     fail if there are no Endpoints connected (Richard Zhu)

  Loongson PCIe controller driver:

   - Add ACPI and MCFG support for Loongson LS7A (Huacai Chen)

   - Avoid config reads to non-existent LS2K/LS7A devices because a
     hardware defect causes machine hangs (Huacai Chen)

   - Work around LS7A integrated devices that report incorrect Interrupt
     Pin values (Jianmin Lv)

  Marvell Aardvark PCIe controller driver:

   - Add support for AER and Slot capability on emulated bridge (Pali
     Rohár)

  MediaTek PCIe controller driver:

   - Add Airoha EN7532 to DT binding (John Crispin)

   - Allow building of driver for ARCH_AIROHA (Felix Fietkau)

  MediaTek PCIe Gen3 controller driver:

   - Print decoded LTSSM state when the link doesn't come up (Jianjun
     Wang)

  NVIDIA Tegra194 PCIe controller driver:

   - Convert DT binding to json-schema (Vidya Sagar)

   - Add DT bindings and driver support for Tegra234 Root Port and
     Endpoint mode (Vidya Sagar)

   - Fix some Root Port interrupt handling issues (Vidya Sagar)

   - Set default Max Payload Size to 256 bytes (Vidya Sagar)

   - Fix Data Link Feature capability programming (Vidya Sagar)

   - Extend Endpoint mode support to devices beyond Controller-5 (Vidya
     Sagar)

  Qualcomm PCIe controller driver:

   - Rework clock, reset, PHY power-on ordering to avoid hangs and
     improve consistency (Robert Marko, Christian Marangi)

   - Move pipe_clk handling to PHY drivers (Dmitry Baryshkov)

   - Add IPQ60xx support (Selvam Sathappan Periakaruppan)

   - Allow ASPM L1 and substates for 2.7.0 (Krishna chaitanya chundru)

   - Add support for more than 32 MSI interrupts (Dmitry Baryshkov)

  Renesas R-Car PCIe controller driver:

   - Convert DT binding to json-schema (Herve Codina)

   - Add Renesas RZ/N1D (R9A06G032) to rcar-gen2 DT binding and driver
     (Herve Codina)

  Samsung Exynos PCIe controller driver:

   - Fix phy-exynos-pcie driver so it follows the 'phy_init() before
     phy_power_on()' PHY programming model (Marek Szyprowski)

  Synopsys DesignWare PCIe controller driver:

   - Simplify and clean up the DWC core extensively (Serge Semin)

   - Fix an issue with programming the ATU for regions that cross a 4GB
     boundary (Serge Semin)

   - Enable the CDM check if 'snps,enable-cdm-check' exists; previously
     we skipped it if 'num-lanes' was absent (Serge Semin)

   - Allocate a 32-bit DMA-able page to be MSI target instead of using a
     driver data structure that may not be addressable with 32-bit
     address (Will McVicker)

   - Add DWC core support for more than 32 MSI interrupts (Dmitry
     Baryshkov)

  Xilinx Versal CPM PCIe controller driver:

   - Add DT binding and driver support for Versal CPM5 Gen5 Root Port
     (Bharat Kumar Gogada)"

<title>phy: samsung: phy-exynos-pcie: sanitize init/power_on callbacks</title>

<id>f2812227bb07e2eaee74253f11cea1576945df31</id>
<content type='text'>
The exynos-pcie driver called phy_power_on() before phy_init() for some
historical reasons. However the generic PHY framework assumes that the
proper sequence is to call phy_init() first, then phy_power_on(). The
operations done by both functions should be considered as one action and as
such they are called by the exynos-pcie driver (without doing anything
between them). The initialization is just a sequence of register writes,
which cannot be altered without breaking the hardware operation.

To match the generic PHY framework requirement, simply move all register
writes to the phy_init()/phy_exit() and drop power_on()/power_off()
callbacks. This way the driver will also work with the old (incorrect)
PHY initialization call sequence.

Instead of using separated clock manipulation, this converts the phy
clock usage to be clk_bulk APIs. By using this, we can completely
remove has_symbol_clk check and symbol clk variables.
Furthermore, clk_get should be moved to probe because there is no need
to get them in the phy_init callback.

Move CDR lock offset to drv data so that it can be extended for other SoCs
which are having CDR lock at different register offset.

For exynos auto v9's UFS MPHY, We should use 0x50 offset of TSRV register
configurations. So, it must be

s/PHY_TRSV_REG_CFG/PHY_TRSV_REG_CFG_AUTOV9/g
