This series of patches introduces the GCLK as a clock source for
the baudrate generator of UART on sama5d2 SoCs. Unlike the serial mode of
the USART offered by FLEXCOM, the UART does not provide a fractional part
that can be added to the clock divisor to obtain a more accurate result,
which greatly decreases the flexibility available for producing a higher
variety of baudrates. Now, with the last patch of the series, the driver
will check for a GCLK in the DT. If provided, whenever `atmel_set_termios`
is called, unless there is a fractional part, the driver will compare the
error rate between the desired baudrate and the actual baudrate obtained
through each of the available clock sources and will choose the clock source
with the lowest error rate. While at it, convert the DT binding
for UART/USART to json-schema, update the FLEXCOM binding to reference the
new UART/USART binding (while differentiating between the SPI of USART and the
SPI of FLEXCOM) and do some small DT related fixups.
The DT bindings related patches of this patch series depend on this patch
series converting atmel-flexcom bindings to json-schema:
https://lore.kernel.org/linux-arm-kernel/20220916075744.1879428-1-kavyasree.kotagiri@microchip.com/
v1 -> v2:
- [PATCH 3] dt-bindings: mfd: atmel,sama5d2-flexcom: Add SPI child node ref
binding:
- use full schema paths
- [PATCH 5] dt-bindings: serial: atmel,at91-usart: convert to json-schema
- only do what the commit says, split the addition of other compatibles
(PATCH 6) and properties (PATCH 13) in other patches
- remove unnecessary "|"'s
- mention header in `atmel,usart-mode`'s description
- place `if:` under `allOf:`
- respect order of spi0's DT properties: compatible, then reg then the
reset of properties
- two new baudrate clock source related patches:
[PATCH 9] tty: serial: atmel: Add definition for GCLK as baudrate source clock
+
[PATCH 10] tty: serial: atmel: Define BRSRCCK bitmask of UART IP's Mode
Register:
- v1's bitfield definition of GCLK was wrong, so add two more patches:
- one for the definition of GCLK of USART IP's
- one for the definition of BRSRCCK bitmask and its bitfields
for UART IP's
- a new cleanup related patch that introduces a new struct atmel_uart_port field:
[PATCH 11] tty: serial: atmel: Only divide Clock Divisor if the IP is USART:
- this ensures a division by 8 which is unnecessary and unappliable to
UART IP's is only done for USART IP's
- four new patches regarding DT fixes and a SPI binding update that I came
upon:
[PATCH 1] spi: dt-bindings: atmel,at91rm9200-spi: Add DMA related properties
[PATCH 2] ARM: dts: at91: sama7g5: Swap rx and tx for spi11
[PATCH 4] ARM: dts: at91: sam9x60ek: Add DBGU compatibles to uart1
[PATCH 6] dt-bindings: serial: atmel,at91-usart: Highlight SAM9X60 incremental
- [PATCH 12] tty: serial: atmel: Make the driver aware of the existence of GCLK
- take into account the different placement of the baudrate clock source
into the IP's Mode Register (USART vs UART)
- don't check for atmel_port->gclk != NULL
- use clk_round_rate instead of clk_set_rate + clk_get_rate
- remove clk_disable_unprepare from the end of the probe method
v2 -> v3:
- Re-order the patches as suggested by Krzysztof Kozlowski:
1. DTS changes needed for aligning to schema.
2. all bindings
3. rest
- New DT consistency related patch:
[PATCH 3] ARM: dts: at91: Add `atmel,usart-mode` required property to serial
nodes
- [PATCH 6] dt-bindings: serial: atmel,at91-usart: convert to json-schema:
- Check value of `atmel,usart-mode` instead of the node regex
- Define all properties top level and disallow them explicitly for other type,
since additionalProperties:false conflicts with referencing other schemas
- Remove useless else if: after else:
- [PATCH 7] dt-bindings: serial: atmel,at91-usart: add SAM9260 compatibles to
SAM9X60:
- Use the commit message suggested by Krzysztof Kozlowski
- [PATCH 8] dt-bindings: mfd: atmel,sama5d2-flexcom: Add USART child node ref
binding
- Compare devices based on the compatible instead of the clock
- [PATCH 12] tty: serial: atmel: Only divide Clock Divisor if the IP is USART
- Use ATMEL_US_CD instead of 65535
- [PATCH 14] tty: serial: atmel: Make the driver aware of the existence of GCLK
- add `gclk_fail` goto
- replace `goto err` with `goto err_clk_disable_unprepare;`
v3 -> v4:
- Remove the first 4 patches as they have already been applied

https://lore.kernel.org/linux-arm-kernel/4b23db7d-d6b2-6c93-01f7-6a3b86f403d1@microchip.com/

Another functionality of FLEXCOM is that of SPI. In order for
the proper validation of the SPI children nodes through the binding
to occur, the proper binding for SPI must be referenced.

Convert at91 USART DT Binding for Atmel/Microchip SoCs to
json-schema format. Furthermore, move this binding to the
serial directory, since binding directories match hardware,
unlike the driver subsystems which match Linux convention.

-- dma bindings for dma transfer:
- - dmas: DMA specifier, consisting of a phandle to DMA controller node,
- memory peripheral interface and USART DMA channel ID, FIFO configuration.
- The order of DMA channels is fixed. The first DMA channel must be TX

- Refer to dma.txt and atmel-dma.txt for details.
- - dma-names: "tx" for TX channel.
- "rx" for RX channel.
- The order of dma-names is also fixed. The first name must be "tx"
- and the second one must be "rx" as in the examples below.

Require SAM9260 fallback compatible for SAM9X60, because SAM9X60 is
fully compatible with SAM9260 and Linux driver requires the latter.

FLEXCOM, among other functionalities, has the ability to offer the USART
serial communication protocol. To have the FLEXCOM binding properly
validate its USART children nodes, we must reference the correct binding.
To differentiate between the SPI of FLEXCOM and the SPI of USART in SPI
mode, use the compatible string.

The Devicetree nodes for FLEXCOM's USART can also have an alternative
clock source for the baudrate generator (other than the peripheral
clock), namely the Generick Clock. Thus make the binding aware of
this clock that someone may place in the clock related
properties of the USART node.

Make sure that the driver only divides the clock divisor if the
IP handled at that point is USART, since UART IP's do not support
implicit peripheral clock division. Instead, in the case of UART,
go with the highest possible clock divisor.

Previously, the atmel serial driver did not take into account the
possibility of using the more customizable generic clock as its
baudrate generator. Unless there is a Fractional Part available to
increase accuracy, there is a high chance that we may be able to
generate a baudrate closer to the desired one by using the GCLK as the
clock source. Now, depending on the error rate between
the desired baudrate and the actual baudrate, the serial driver will
fallback on the generic clock. The generic clock must be provided
in the DT node of the serial that may need a more flexible clock source.

v1 -> v2:
- take into account the different placement of the baudrate clock source
into the IP's Mode Register (USART vs UART)
- don't check for atmel_port->gclk != NULL
- use clk_round_rate instead of clk_set_rate + clk_get_rate
- remove clk_disable_unprepare from the end of the probe method
v2 -> v3:
- add the error rate calculation function as an inline function instead of
a macro definition
- add `gclk_fail` goto
- replace `goto err` with `goto err_clk_disable_unprepare;`
v3 -> v4:
- Nothing, this was previously [PATCH 14]

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.
Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Hello, thank you for checking :). The above link issues a 404.
Everything should be fine though once all of the below are merged:
https://lore.kernel.org/linux-arm-kernel/53e72e5d-47fc-403d-c969-61b267a9ff15@microchip.com/
https://lore.kernel.org/linux-arm-kernel/1ae89854-74fa-6194-304f-db31d56d3674@microchip.com/
together with the patch series that I linked into the cover letter as a
dependence:
https://lore.kernel.org/linux-arm-kernel/20220916075744.1879428-1-kavyasree.kotagiri@microchip.com/
Thank you,
Sergiu

If this condition fails and you previously used GCLK for clock generation
you should remove bits ATMEL_US_USCLKS or ATMEL_UA_BRSRCCK from mode
variable, to avoid configuring MR with GCLK support and clock not being
properly setup.

This will not happen, since the code block placed at the very start of
atmel_set_termios()
/* reset the mode, clock divisor, parity, stop bits and data size */
mode &= ~(ATMEL_US_USCLKS | ATMEL_US_CHRL | ATMEL_US_NBSTOP |
ATMEL_US_PAR | ATMEL_US_USMODE);
will still clear the ATMEL_UA_BRSRCCK bitfield since it is the same as
the ATMEL_US_NBSTOP bitfield.
It is ugly and it has been working so far just through the coincidence
of the bitfields placement.
I did not want to change those lines as I did not really think of them
as worth being part of this patch series (PATCH 8 of this series is an
exception as it does introduce the needed is_usart boolean).
I will send a patch regarding this, but separately since it is more like
a pure cleanup related PATCH, in my opinion.
