====================
net: dsa: lan9303: Fix MDIO issues.
This series fix the MDIO interface for the lan9303 DSA driver.
Bugs found after testing on actual HW.
This series is extracted from the first patch of my first large
series. Significant changes from that version are:
- use mdiobus_write_nested, mdiobus_read_nested.
- EXPORT lan9303_indirect_phy_ops
Unfortunately I do not have access to i2c based system for
testing.
Changes from first version:
- Change EXPORT_SYMBOL to EXPORT_SYMBOL_GPL

Indirect access (PMI) to phy register only work in I2C mode. In
MDIO mode phy registers must be accessed directly. Introduced
struct lan9303_phy_ops to handle the two modes.

Preparing for the following fix of MDIO phy access:
Renamed functions that access PHY 1 and 2 indirectly through PMI
registers.
lan9303_port_phy_reg_wait_for_completion() to
lan9303_indirect_phy_wait_for_completion()
lan9303_port_phy_reg_read() to
lan9303_indirect_phy_read()
lan9303_port_phy_reg_write() to
lan9303_indirect_phy_write()
Also changed "val" parameter of lan9303_indirect_phy_write() to u16,

It's a hardware bug, all window's overlay channel reset
value is same, hardware overlay would be die.
so we must initial difference id for each overlay channel.
The Channel register is supported on all vop will full design.
Following is the details for this register
VOP_WIN0_CTRL2
bit[7:4] win_rid_win0_cbr
axi read id of win0 cbr channel
bit[3:0] win_rid_win0_yrgb

Since the drm atomic framework, only a small part of the vop
register needs sync write, Currently seems only following registers
need sync write:
cfg_done, standby and interrupt related register.
All ctrl registers are using the sync write method that is
inefficient, hardcode the write_relaxed flags to vop registers,
then can only do synchronize write for those actual needed register.

it is unreadable, and sometimes we only want to update tiny

This patch drops two incorrect usages of tcm_qla2xxx_free_cmd()
during TMR ABORT within tcm_qla2xxx_handle_data_work() and
tcm_qla2xxx_aborted_task(), which where attempting to dispatch
into workqueue context to do tcm_qla2xxx_complete_free() and
subsequently invoke transport_generic_free_cmd().
This is incorrect because during TMR ABORT target-core will
drop the outstanding se_cmd->cmd_kref references once it has
quiesced the se_cmd via transport_wait_for_tasks(), and in
the case of qla2xxx it should not attempt to do it's own
transport_generic_free_cmd() once the abort has occured.
As reported by Pascal, this was originally manifesting as a
BUG_ON(cmd->cmd_in_wq) in qlt_free_cmd() during TMR ABORT,
with a LIO backend that had sufficently high enough WRITE
latency to trigger a host side TMR ABORT_TASK.
(v2: Drop the qla_tgt_cmd->write_pending_abort_comp changes,
as they will be addressed in a seperate series)

The current logic of calculating sg_nents can fail
if data_offset % PAGE_SIZE is not zero.
For example -
PAGE_SIZE = 4096
data_len = 3072
data_offset = 3072
As per current logic
sg_nents = max(1UL, DIV_ROUND_UP(data_len, PAGE_SIZE));
sg_nents = max(1UL, DIV_ROUND_UP(3072, 4096));
sg_nents = 1
But as data_offset % PAGE_SIZE = 3072 we should skip 3072 bytes
skip = 3K
sg_nents = max(1UL, DIV_ROUND_UP(3K(skip) + 3K(data_len), 4K(PAGE_SIZE));
sg_nents = 2;
This patch fixes this issue by adding skip to data_len.

On receiving text request iscsi-target allocates buffer for
payload in iscsit_handle_text_cmd() and assigns buffer pointer
to cmd->text_in_ptr, this buffer is currently freed in
iscsit_release_cmd(), if iscsi-target sets 'C' bit in text
response then it will receive another text request from the
initiator with ttt != 0xffffffff in this case iscsi-target
will find cmd using itt and call iscsit_setup_text_cmd()
which will set cmd->text_in_ptr to NULL without freeing
previously allocated buffer.
This patch fixes this issue by calling kfree(cmd->text_in_ptr)
in iscsit_setup_text_cmd() before assigning NULL to it.
For the first text request cmd->text_in_ptr is NULL as
cmd is memset to 0 in iscsit_allocate_cmd().

As raw device io functions are not portable and don't handle byte-order
(triggering suspicion that endianness isn't handled well) switch to
using the standard api.
Since MC expects LE byte-order and the upper layers already take care
of that, we need to trick the device io api by doing a LE -> CPU
conversion just before calling it. This way, the CPU -> LE conversion
done in the api puts the data back in the right byte-order. Obviously,
for reads the extra step is mirrored: there's a CPU -> LE conversion
following the API call.
