Hi all,
This is v3. The only objection I can imagine is about "fsl,device-id".
Though in the v2 nobody complained, thus it's stayed intact.
If you want to, complain now. I'll give up and will remove it. ;-)
Changelog:
v2 -> v3
o Device tree:
- completely removed mmc node;
- removed pio-handles and pio-maps.
o board file:
- Instead of par_io_of_config(), now par_io_config_pin() used to
configure GPIO pins, which does not require device tree node.
v1 -> v2
o Device tree:
- cosmetic cleanups (@01 -> @1);
- device-id renamed to fsl,device-id;
- removed max-chipselect and sysclk properties from spi node;
- removed chipselect property from mmc node, now reg property
used for this purpose, thereby address-cells and size-cells
added to the spi node;
- other non-mandatory (device-id, device_type, compatible, ...)
properties removed from mmc node, today board file is using
of_find_node_by_name(), instead of of_find_compatible_node();
- "qe" mode renamed to "cpu-qe".
o board file <-> fsl_soc interaction
- fsl_soc no longer scans for SPI nodes in the arch initcall.
Also it's no longer exports any global variables. Instead, it's
export fsl_spi_init function now, which accepts pointer to the
fsl_spi_board_info structure;
- board file fills fsl_spi_board_info structure and issues
fsl_spi_init(), which register SPI devices and SPI board infos.
Various sanity checks also perfromed.
I'd want to note that if spi_mpc83xx will be converted to
of_platform_driver then the scheme described above will not
work anymore, and I'll have to revert back ugly hacks:
global variables for activate/deactivate_cs functions. I see
no other options.
Thanks,
