2021-03-16can: c_can: move runtime PM enable/disable to c_can_platformTong Zhang
Currently doing modprobe c_can_pci will make the kernel complain: Unbalanced pm_runtime_enable! this is caused by pm_runtime_enable() called before pm is initialized. This fix is similar to 227619c3ff7c, move those pm_enable/disable code to c_can_platform.

2021-01-14can: dev: can_get_echo_skb(): extend to return can frame lengthMarc Kleine-Budde
In order to implement byte queue limits (bql) in CAN drivers, the length of the CAN frame needs to be passed into the networking stack after queueing and after transmission completion. To avoid to calculate this length twice, extend can_get_echo_skb() to return that value. Convert all users of this function, too.

2021-01-14can: dev: can_put_echo_skb(): extend to handle frame_lenVincent Mailhol
Add a frame_len argument to can_put_echo_skb() which is used to save length of the CAN frame into field frame_len of struct can_skb_priv so that it can be later used after transmission completion. Convert all users of this function, too. Drivers which implement BQL call can_put_echo_skb() with the output of can_skb_get_frame_len(skb) and drivers which do not simply pass zero as an input (in the same way that NULL would be given to can_get_echo_skb()). This way, we have a nice symmetry between the two echo functions.

2020-11-30can: c_can: c_can_power_up(): fix error handlingZhang Qilong
In the error handling in c_can_power_up(), there are two bugs: 1) c_can_pm_runtime_get_sync() will increase usage counter if device is not empty. Forgetting to call c_can_pm_runtime_put_sync() will result in a reference leak here. 2) c_can_reset_ram() operation will set start bit when enable is true. We should clear it in the error handling. We fix it by adding c_can_pm_runtime_put_sync() for 1), and c_can_reset_ram(enable is false) for 2) in the error handling.

The naming of can_dlc as element of struct can_frame and also as variable name is misleading as it claims to be a 'data length CODE' but in reality it always was a plain data length. With the indroduction of a new 'len' element in struct can_frame we can now remove can_dlc as name and make clear which of the former uses was a plain length (-> 'len') or a data length code (-> 'dlc') value.

The priv->device pointer for c_can_pci is never set, but it is used without a NULL check in c_can_start(). Setting it in c_can_pci_probe() like c_can_plat_probe() prevents c_can_pci.ko from crashing, with and without CONFIG_PM. This might also cause the pm_runtime_*() functions in c_can.c to actually be executed for c_can_pci devices - they are the only other place where priv->device is used, but they all contain a null check.

2015-07-12can: c_can: Fix default pinmux glitch at initJ.D. Schroeder
The previous change 3973c526ae9c (net: can: c_can: Disable pins when CAN interface is down) causes a slight glitch on the pinctrl settings when used. Since commit ab78029 (drivers/pinctrl: grab default handles from device core), the device core will automatically set the default pins. This causes the pins to be momentarily set to the default and then to the sleep state in register_c_can_dev(). By adding an optional "enable" state, boards can set the default pin state to be disabled and avoid the glitch when the switch from default to sleep first occurs. If the "enable" state is not available c_can_pinctrl_select_state() falls back to using the "default" pinctrl state. [Roger Q] - Forward port to v4.2 and use pinctrl_get_select(). Signed-off-by: J.D.

use of regmap_read() and regmap_write() in c_can_hw_raminit_syscon() is not safe as the RAMINIT register can be shared between different drivers at least for TI SoCs. To make the modification atomic we switch to using regmap_update_bits(). regmap_update_bits() skips writing to the register if it's read content is the same as what is going to be written. This causes an issue for us when we need to clear the DONE bit with the initial condition START:0, DONE:1 as DONE bit must be written with 1 to clear it. So we defer the clearing of DONE bit to later when we set the START bit. There we are sure that START bit is changed from 0 to 1 so the write of 1 to already set DONE bit will happen.

2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2014-07-25can: c_can_platform: Fix raminit, use devm_ioremap() instead of ↵George Cherian
devm_ioremap_resource() The raminit register is shared register for both can0 and can1. Since commit: 32766ff net: can: Convert to use devm_ioremap_resource devm_ioremap_resource() is used to map raminit register. When using both interfaces the mapping for the can1 interface fails, leading to a non functional can interface.

Conflicts: drivers/net/bonding/bond_alb.c drivers/net/ethernet/altera/altera_msgdma.c drivers/net/ethernet/altera/altera_sgdma.c net/ipv6/xfrm6_output.c Several cases of overlapping changes. The xfrm6_output.c has a bug fix which overlaps the renaming of skb->local_df to skb->ignore_df. In the Altera TSE driver cases, the register access cleanups in net-next overlapped with bug fixes done in net. Similarly a bug fix to send ALB packets in the bonding driver using the right source address overlaps with cleanups in net-next. Signed-off-by: David S. Miller <davem@davemloft.net>
