Certain platforms like TI's J721E using Cadence PCIe IP can perform only
32-bit accesses for reading or writing to Cadence registers. Convert all
read and write accesses to 32-bit in Cadence PCIe driver in preparation
for adding PCIe support in TI's J721E SoC.

commit bd22885aa188 ("PCI: cadence: Refactor driver to use as a core
library") while refactoring the Cadence PCIe driver to be used as
library, removed pm_runtime_get_sync() from cdns_pcie_ep_setup()
and cdns_pcie_host_setup() but missed to remove the corresponding
pm_runtime_put_sync() in the error path. Fix it here.

Add a macro for aligning down a pointer. This is useful to get an
aligned register address when a device allows only word access and
doesn't allow half word or byte access.

* [PATCH v5 00/14] Add PCIe support to TI's J721E SoC
From: Kishon Vijay Abraham I @ 2020-05-22 3:36 UTC (permalink / raw)

TI's J721E SoC uses Cadence PCIe core to implement both RC mode
and EP mode.
The high level features are:
*) Supports Legacy, MSI and MSI-X interrupt
*) Supports upto GEN4 speed mode
*) Supports SR-IOV
*) Supports multiple physical function
*) Ability to route all transactions via SMMU
This patch series
*) Add support in Cadence PCIe core to be used for TI's J721E SoC
*) Add a driver for J721E PCIe wrapper
v1 of the series can be found @ [1]
v2 of the series can be found @ [2]
v3 of the series can be found @ [5]
v4 of the series can be found @ [6]
Changes from v4:
1) Added Reviewed-by: & Acked-by: tags from RobH
2) Removed un-used accessors for pcie-cadence.h and removed having ops
for read/write accessors
3) Updated cdns,cdns-pcie-host.yaml to remove "mem" from reg
Changes from v3:
1) Changed the order of files in MAINTAINTERS file to fix Joe's comments
2) Fixed indentation and added Reviewed-by: Rob Herring <robh@kernel.org>
3) Cleaned up computing msix_tbl
4) Fixed RobH's comment on J721E driver
Changes from v2:
1) Converting Cadence binding to YAML schema was done as a
separate series [3] & [4]. [3] is merged and [4] is
pending.
2) Included MSI-X support in this series
3) Added link down interrupt handling (only error message)
4) Rebased to latest 5.7-rc1
5) Adapted TI J721E binding to [3] & [4]
Changes from v1:
1) Added DT schemas cdns-pcie-host.yaml, cdns-pcie-ep.yaml and
cdns-pcie.yaml for Cadence PCIe core and included it in
TI's PCIe DT schema.
2) Added cpu_addr_fixup() for Cadence Platform driver.
3) Fixed subject/description/renamed functions as commented by
Andrew Murray.

Okay, I'll remove ops for read/write accessors.

Ok, that is, i don't need to modify the doc in kernel, just create a pull request in github [1]?

I did like this in my previous version, such as v5. After discussed with James, i modified it to the current way.
We think the existing behavior should be unchanged, which helps with keeping compatibility with existing
user-space and older kdump kernels.
The comments from James:
> linux,usable-memory-range = <BASE1 SIZE1 [BASE2 SIZE2]>.
Won't this break if your kdump kernel doesn't know what the extra parameters are?
Or if it expects two ranges, but only gets one? These DT properties should be treated as
ABI between kernel versions, we can't really change it like this.
I think the 'low' region is an optional-extra, that is never mapped by the first kernel. I
think the simplest thing to do is to add an 'linux,low-memory-range' that we
memblock_add() after memblock_cap_memory_range() has been called.
If its missing, or the new kernel doesn't know what its for, everything keeps working.

In-Reply-To: <20200522030743.10204-1-frank@allwinnertech.com>
A100 perf1 is an Allwinner A100-based SBC, with the following features:
- 1GiB DDR3 DRAM
- AXP803 PMIC
- 2 USB 2.0 ports
- MicroSD slot and on-board eMMC module
- on-board Nand flash
- ···
Adds initial support for it, including the UART.

* [PATCH v3 2/2] arm64: dts: imx8mn-ddr4-evk: correct ldo1/ldo2 voltage range

In-Reply-To: <1590144291-18526-1-git-send-email-yibin.gong@nxp.com>
Correct ldo1 voltage range from wrong high group(3.0V~3.3V) to low group
(1.6V~1.9V) because the ldo1 should be 1.8V. Actually, two voltage groups
have been supported at bd718x7-regulator driver, hence, just corrrect the
voltage range to 1.6V~3.3V. For ldo2@0.8V, correct voltage range too.
Otherwise, ldo1 would be kept @3.0V and ldo2@0.9V which violate i.mx8mn
datasheet as the below warning log in kernel:
[ 0.995524] LDO1: Bringing 1800000uV into 3000000-3000000uV
[ 0.999196] LDO2: Bringing 800000uV into 900000-900000uV

Well, strictly speaking R3 added microMIPS support, which was all but
minor (of course there were minor updates too, such as 2008-NaN support).

Andrew, many customers require the wol feature, NXP NPI release always support
the wol feature to match customers requirement.
And some customers' board only design one ethernet instance based on imx6sx/imx7d/
Imx8 serial, but which instance we never know, maybe enet1, maybe enet2. So we should
supply different values for gpr.
So, it is very necessary to support wol feature for multiple instances.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces two DW SPI legacy
bare text bindings with YAML file. As before the bindings file states
that the corresponding dts node is supposed to be compatible either
with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel
vendors-specific controllers, to have registers, interrupts and clocks
properties. Though in case of Microsemi version of the controller
there must be two registers resources specified. Properties like
clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device
sub-nodes are optional.

* [PATCH v4 14/16] spi: dw: Add DMA support to the DW SPI MMIO driver
From: Serge Semin @ 2020-05-22 0:08 UTC (permalink / raw)

In-Reply-To: <20200522000806.7381-1-Sergey.Semin@baikalelectronics.ru>
Since the common code in the spi-dw-dma.c driver is ready to be used
by the MMIO driver and now provides a method to generically (on any
DT or ACPI-based platforms) retrieve the Tx/Rx DMA channel handlers,
we can use it and a set of the common DW SPI DMA callbacks to enable
DMA at least for generic "snps,dw-apb-ssi" and "snps,dwc-ssi-1.01a"
devices.

Seeing all of the DW SPI driver components like DW SPI DMA/PCI/MMIO
depend on the DW SPI core code it's better to use the if-endif
conditional kernel config statement to signify that common dependency.

Since there is a generic method available to initialize the DW SPI DMA
interface on any DT and ACPI-based platforms, which in general can be
designed with not only DW DMAC but with any DMA engine on board, we can
freely remove the CONFIG_DW_DMAC_PCI config from dependency list of
CONFIG_SPI_DW_DMA. Especially seeing that we don't use anything DW DMAC
specific in the new driver.

It isn't good to have numeric literals in the code especially if there
are multiple of them and they are related. Let's replace the Tx and Rx
burst level literals with the corresponding constants.

In-Reply-To: <20200522000806.7381-1-Sergey.Semin@baikalelectronics.ru>
Each channel of DMA controller may have a limited length of burst
transaction (number of IO operations performed at ones in a single
DMA client request). This parameter can be used to setup the most
optimal DMA Tx/Rx data level values. In order to avoid the Tx buffer
overrun we can set the DMA Tx level to be of FIFO depth minus the
maximum burst transactions length. To prevent the Rx buffer underflow
the DMA Rx level should be set to the maximum burst transactions length.
This commit setups the DMA channels and the DW SPI DMA Tx/Rx levels
in accordance with these rules.
