The Amlogic Meson PCIe host controller is based on the Synopsys DesignWare
PCI core. This patchset add the driver and dt-bindings of the controller.

Changes since v7: [6]
 - include files in alphabetical order
 - get rid of unused MACROs and variables
 - optimize meson_pcie_link_up() while loop
 - correct cover-letter version

Changes since v6: [5]
 - fix bad usage of ERR_PTR(ENXIO)
 - fix meson_pcie_rd_own_conf() when read PCI_CLASS_DEVICE reg 

Changes since v5: [4]
 - update MAINTAINER file in alphabetical order
 - remove meaningless comment
 - use ERR_PTR function instead of (void *) cast
 - use is_power_of_2(size) instead of size & (size - 1)
 - add comment for PCI_CLASS_REVISION register operation
 
Changes since v4: [3]
 - fix kbuild test robot and compile warnings

Changes since v3: [2]
 - modify subject format
 - update Kconfig
 - update MAINTAINER file
 - add comment and error handle for meson_pcie_get_mem_shared()
 - drop useless initialization code
 - add comment for meson_size_to_payload()
 - optimize meson_pcie_establish_link() return code
 - optimize meson_pcie_enable_interrupts() redundant function
 - drop device_attch related code
 - drop dw_pcie_ops read_dbi and write_dbi function
 - add error handle for meson_add_pcie_port() when probe

Changes since v2: [1]
 - abandon phy driver, move reset to the controller
 - use devm_add_action_or_reset() to use clock res
 - format correcting

Changes since v1: [0]
 - use gpio lib instead open code
 - move 'apb' and 'port' reset from phy driver
 - format correcting
