In order to prevent overran of IRQ polarity via FW the polarity setting move after
FW download and before IRQ enable.

Definitions to support wl128x:
- New FW file name
- Chip ID
- New PLL Configuration Algorithm macros that will be used at wl128x
boot stage
- Rename NVS macro name: wl127x and wl128x are using the same NVS
file name. However, the ini parameters between of them are
different. The driver will validate the correct NVS size in
wl1271_boot_upload_nvs().

New acx command that sets: Rx fifo enable reduced bus transactions
in RX path. Tx bus transactions padding to SDIO block size that
improve preference in Tx and essential for working with SDIO HS (48Mhz).
The max SDIO block size is 256 when working with Tx bus transactions
padding to SDIO block.
Add new ops to SDIO & SPI that handles the win size change in case of
transactions padding (relevant only for SDIO).

From: Luciano Coelho @ 2011-03-07 12:53 UTC (permalink / raw)
To: shahar_l; +Cc: coelho, linux-wireless
This patch fixes up some issues with patch 03/15 in the wl128x support
series:
* Fix endianess issues;
* Simplify sdio-specific block_size handling;
* Minor changes in comments
This has been compile-tested only. I will test this changes after I
go through the whole series and, if everything is still ok, I'll merge
this patch into 03/15.

This patch fixes up some issues with patch 03/15 in the wl128x support
series:
* Fix endianess issues;
* Simplify sdio-specific block_size handling;
* Minor changes in comments
This has been compile-tested only. I will test this changes after I
go through the whole series and, if everything is still ok, I'll merge
this patch into 03/15.

This is wrong. You're just setting the local nvs variable to NULL.
It's wl->nvs that should be set to NULL instead.

Same thing here. I have fixed these.
This was causing very bad behaviour when the NVS was with the wrong
size, because we were not setting wl->nvs to NULL, but were setting
wl->nvs_len to 0.

Boot sequence support FREF clock and TCXO clock.
WL128x has two clocks input - TCXO and FREF.
TCXO is the main clock of the device, while FREF is used to sync
between the GPS and the cellular modem.
Auto-detection checks where TCXO is 32.736MHz or 16.368MHz, in that
case the FREF will be used as the WLAN/BT main clock.

Can you explain why you changed the wl127x part as well? For wl127x
you're essentially changing:
clk |= (wl->ref_clock << 1) << 4;
to:
clk |= ((wl->ref_clock & 0x3) << 1) << 4;
This means that CONF_REF_CLK_38_4_M_XTAL will be treated in the same way
as CONF_REF_CLK_19_2_E. Is that right? If it is, it must be addressed
in a separate patch and not as part of the Quattro series.

This implantation is due to the fact only those two bits is valid for
clk setting (from MCP).
CONF_REF_CLK_38_4_M_XTAL should be set as 19M.
I will address is as separate patch.

Thanks! I think there should be a comment with an explanation that
CLK_38_4_M_XTAL should be set as CLK_19_2_E and why.

This patch fixes up some issues with patch 06/15 in the wl128x support
series:
* Remove unnecessary else block in wl128x_switch_fref;
* Remove unnecessary change in main.c;
* Remove some unnecessary debug prints and comments;
* Fix potential use of uninitialized value (pll_config)
* Add more all the defines for HCI_IO_DS_* instead of having them in a comment
This has been compile-tested only. I will test this changes after I
go through the whole series and, if everything is still ok, I'll merge
this patch into 06/15.

I believe that debug should be say in that function that check the ref value.

This implantation is due to the fact only those two bits is valid for
clk setting (from MCP).
CONF_REF_CLK_38_4_M_XTAL should be set as 19M.
I will address is as separate patch.

Sorry, I disagree. This debug message is actually saying what is
happening when the ref_clock value is *_XTAL and what happens cannot be
seen in this part of the code, only in the part that calls this
function.
In fact, I almost removed this debug message completely, because there
are way too many debug messages that are good during implementation, but
shouldn't go out when the implementation is working.
I'll keep it (for now) after the function is called.

This comment is useless in this part of the code. If it should be
somewhere, it should be where the macros are defined. But even there, I
think it doesn't add any value, because it's so obvious.

Support dynamic TX mem blocks in the driver to wl128x FW that
supports moving TX mem blocks to RX in case the RX path is loaded.
The TX blocks available to use updated dynamically.
Thanks for Arik Nemtsov <arik@wizery.com> for helping simplify
wl1271_fw_status() code.

The WL12XX_QUIRK_END_OF_TRANSACTION is only enabled for wl127x, so no
need to check that it's not wl128x here.

Same thing here.
I'll remove these unnecessary checks.

Support sending dummy packet to wl128x FW as results of
dummy packet event. That is part of dynamic TX mem blocks mechanism.
Only send dummy packet when not in AP mode (Thanks to
Ido Yariv" <ido@wizery.com> and Arik Nemtsov" <arik@wizery.com> for this one)

You can't change this value in the global array. This needs to be
changed only in the allocated ACX. I'll change it before taking it in.
Also, I think it's cleaner to keep the correct value for wl127x in the
global array (as was before) and only change the value for wl128x here
in this function.

Previously, the value used for wl127x was 50, from the default global
settings. Now you're using 200 for wl127x. This looks suspicious. You
now use 50 (which was the value for wl127x) for wl128x and 200 for
wl127x.
At least the change for wl127x should be done in a separate patch.

It was incorrect value for wl127x. That patch fixes that and set
wl128x value. I can do the fix for wl127x in separate patch.

Okay, so this means that for wl128x we don't need the current patch at
all. The value is already 50, which is good for wl128x. A new patch
for wl127x should be sent separately.

All FW except for 127x AP use 1 spare blocks for TX. Reflect this in
the code.
In case of GEM need 2 spare blocks in STA.

This is a workaround for the HW bug we're encountering when operating
with 48Mhz SDIO clocks. This workaround is currently employed by the MCP
driver as well.
This is not healthy for CPU usage, and UDP TX seems hurt by this change.
TCP RX/TX seems unchanged from Trio or the 1-spare-block FW variant.
With this workaround we get a working AP on Blaze.
