[PATCH v10 0/7] PCI: mediatek: Add new generation controller support

[Jianjun Wang]

From: mtk15901 <jianjun.wang at mediatek.com>

These series patches add pcie-mediatek-gen3.c and dt-bindings file to
support new generation PCIe controller.

Changes in v10:
1. Fix the subject line format in commit message;
2. Use EXPORT_SYMBOL_GPL() to export pci_pio_to_address().

Changes in v9:
1. Use mtk_pcie_parse_port() to get the hw resources;
2. Remove unnecessary logs;
3. Add local IRQ enable status save/restore instead of
   the enable/disable callbacks;
4. Fix typos.

Changes in v8:
1. Add irq_clock to protect IRQ register access;
2. Mask all INTx interrupt when startup port;
3. Remove activate/deactivate callbacks from bottom_domain_ops;
4. Add unmask/mask callbacks in mtk_msi_bottom_irq_chip;
5. Add property information for reg-names.

Changes in v7:
1. Split the driver patch to core PCIe, INTx, MSI and PM patches;
2. Reshape MSI init and handle flow,
   use msi_bottom_domain to cover all sets;
3. Replace readl/writel with their relaxed version;
4. Add MSI description in binding document;
5. Add pl_250m clock in binding document.

Changes in v6:
1. Export pci_pio_to_address() to support compiling as kernel module;
2. Replace usleep_range(100 * 1000, 120 * 1000) with msleep(100);
3. Replace dev_notice with dev_err;
4. Fix MSI get hwirq flow;
5. Fix warning for possible recursive locking in mtk_pcie_set_affinity.

Changes in v5:
1. Remove unused macros
2. Modify the config read/write callbacks, set the config byte field
   in TLP header and use pci_generic_config_read32/write32
   to access the config space
3. Fix the settings of translation window, both MEM and IO regions
   works properly
4. Fix typos

Changes in v4:
1. Fix PCIe power up/down flow
2. Use "mac" and "phy" for reset names
3. Add clock names
4. Fix the variables type

Changes in v3:
1. Remove standard property in binding document
2. Return error number when get_optional* API throws an error
3. Use the bulk clk APIs

Changes in v2:
1. Fix the typo of dt-bindings patch
2. Remove the unnecessary properties in binding document
3. dispos the irq mappings of msi top domain when irq teardown
